Internet Security - Quick Guide


Internet Security - Overview

With the usage of Internet, a number of activities take place in your computer which can be for good or bad and varies from identity thefts to people who hack into computers and steal private passwords, documents and files. The fact is that everything is online and opens us to these frauds and makes us victims, unless you have taken the necessary steps to protect your computer.

It is quite strange that till date, a lot of people don’t give much importance to Internet Security. They think that their computers are invisible, but as soon as they start using their computers for anything that involves logging onto the Internet, they are an easy prey, even for a teenaged hacker.

The following image gives you an idea of how things have changed over the years.

Impact from an Internet Breach

The potential losses in this “cloud” are discussed as follows.

Here is a list of some losses that can have a direct impact on you and others −

  • Losing Your Data − An Internet breach can swipe away all the data that you have gathered over the years.

  • Reputation Loss − Just think your Facebook account or business email have been hacked by a social engineering attack and it sends fake information to your friends, business partners. You will need time to gain back your reputation after such an attack. Or your webpage has been hacked and the hacker puts up an ugly picture on it, so a new customer that is visiting your webpage to get some information will see this picture named “HACKED” and the chances that he will go away without contacting you will be too high.

  • Identity Theft − This is a case where your identity is stolen (photo, name surname, address, and credit card details) and can be used for a crime like making false identity documents or anything else.

Internet Security - Cookies

Cookies are files, generally from the visited webpages, which are stored on a user's computer. They hold a small amount of data, specific to a particular client and website, and can be accessed either by the web server or the client computer which can be usernames, password, session token, etc.

This allows the server to deliver a page personalized to a particular user, or the page itself can contain some script which is aware of the data in the cookie and so is able to carry information from one visit to that website.

Types of Cookies

There are three different types of cookies −

  • Session Cookies − These are mainly used by online shops and allows you to keep items in your basket when shopping online. These cookies expire after a specific time or when the browser is closed.

  • Permanent Cookies − These remain in operation, even when you have closed the browser. They remember your login details and password so you don’t have to type them in every time you use the site. It is recommended that you delete these type of cookies after a specific time.

  • Third-Party Cookies − These are installed by third parties for collecting certain information. For example: Google Maps.

The following screenshot shows where the data of a cookie is stored and to do this, I have used a plugin of Firefox which is called Cookies Manager+. It shows the date when a cookie will expire.

Internet Security - Phishing

Many of us have received similar emails as shown in the following screenshot. They appear as if coming from a genuine source, but in fact if we analyze them a little carefully, they are not. Such emails are called “phishing” because it depends on the users whether they will follow the procedure that the scammer is requesting or if they (user) will delete that email and be safe.

The links in the email may install malware on the user’s device or direct them to a malicious website set up to trick them into divulging personal and financial information, such as passwords, account IDs or credit card details. These techniques are too much in use with cybercriminals, as it is far easier to trick someone into clicking a malicious link in the email than trying to break through a computer’s defenses. Although some phishing emails are poorly written and clearly fake.

How to Detect a Phishing Email?

There are several ways to detect a Phishing Email, some of these methods are discussed here for better understanding.

Spelling and Bad Grammar

Cyber criminals generally make grammar and spelling mistakes because they use dictionary too often to translate in a specific language. If you notice mistakes in an email, it might be a scam.

Links in Email

Links in the email are always with hidden URLs, you don't click on it. Rest your mouse (but don't click) on the link to see if the address matches the link that was typed in the message. In the following example the link reveals the real web address, as shown in the box with the yellow background. The string of cryptic numbers looks nothing like the company's web address.

Links In Emails

Links also may redirect you to .exe, or zipped files. These are known to spread malicious software.

Threats or They are too Good to be True

Cybercriminals often use threats that your security has been compromised. The above screenshot shows it very well. In our case the subject talking about Suspension.


Spoofing Popular Websites or Companies

Scam artists use graphics in email that appear to be connected to legitimate websites, but actually they take you to phony scam sites or legitimate-looking pop-up windows. In our case, there is this email of Amazon which is not a genuine one.

Spoofing Websites


Generally, if it is genuine you will have a personalized email like Dear Mr. John, but the cybercriminals, they don’t know your name except the email address, so they will use just a part of your email in the salutation or a general salutation.


Got Phished by Mistake?

What to do in case you think that by mistake, you got phished? In such a case, you can take the following measures −

  • Change the passwords immediately of the account that you think has been hacked.

  • Check if any money has been withdrawn or any payment done through your account. You can contact your financial institution directly for this.

  • Contact the authority on whose behalf you got that email. You should also report to your account administrator.

Internet Security - Social Network

Social Networking is the use of Internet based on social media systems to get in touch with family, friends, customers, classmates, etc. Social Networking can be done for social purposes, business purposes or both. The programs show the associations between individuals and facilitate the acquisition of new contacts.

Social Networking is becoming more and more popular nowadays. For better understanding of its popularity, see the following graph.

Social Media Usage

As you can see two thirds of the population are using social media which makes it very attractive for cybercriminals. They can hack an account of others and make profiles for different purposes which can be used as a bridge to attack their social network, or to get their data.

Profile Impersonation

The top threat for year 2015 in social media was Profile Impersonation. Many of us have seen in Facebook the fake profiles of someone that we know. This generally is made into a phishing link to your known social network. One precaution to avoid such phishing is to report the fake account immediately and let the concerned authorities take action. If you accept the friend request sent by such a fake profile, all your personal photos and other data can be stolen from your account and the hacker can use it in different ways.

Internet Security - Child Safety

In this section we will focus on Children’s safety as the Internet is a fact for all of us and it interferes in our daily lives. We will discuss the practical steps that we need to take without bothering them (children) and some programs used for this purpose.

Why is it so Important?

Generally, children or teenagers like to participate in chat rooms or social media which offer chats too, for many reasons to express themselves, curiosity, talk to other children around the world and to share their experiences. But on the other side, the kids need to know that in this environment there are people with bad intensions too. So the kids can be potential victims to bullies, harassments, etc. Also they can reveal information regarding the family members to other unknown persons with bad intentions.

As Internet is a place where anonymity can remain for the moment, it is a dangerous asset for unsupervised children. A kid or a teenager can be seduced by a stranger, who is polite at first contact and is willing to listen to them but on the other side he can be a pedophile luring who’s only aim is to have a meeting which can lead to a sexual assault.

Even a small information that can be given by the child can be very dangerous because the attacker can trace down the information given by the kid.

As mentioned in the games section, many of them allow for voice as well text chatting between sessions. Kids should be prudent while using gaming chats in the same way as they do for chat rooms and social media, and should be cautious of overly eager new friends who ask them insisting for their mobile phone number, their address, or a face-toface meeting.

Social Rules Regarding Child Internet Safety

Here are a few simple pointers regarding child Internet safety.

The computer should be placed in the living room with the monitor facing towards the room so there nothing to hide. Always check if your child quickly changes the screen when you pass by, or is hiding files or disks — someone may have sent them inappropriate content like pornography.

Discuss with your child exactly what is OK and what is not OK regarding what kind of websites are appropriate for them, which chat rooms to visit, and what kinds of things they can talk about there. Only let your kids use monitored chat rooms. Avoid “.alt” chat rooms — they focus on alternative topics that may be inappropriate for kids. Get to know your child’s online friends as you do with their school and neighborhood friends. Surf the web and chat online yourself so you understand what it is that your child is doing.

Make clear to your child that they need to tell you if they receive any upsetting messages while chatting, and that you will not be angry with them and ban the Internet as a result. Make it clear to the child that you understand that they cannot control what other people say to them and that they are not to blame if this happens.

Set time limits for Internet usage – Software is available that enforces these limits which we will see in another section. Usage time should not be at late night. Do not permit your child to be left alone in cyberspace for long periods of time — this is when they are ost vulnerable.

Tell your child that people in chat rooms are always strangers who can potentially harm – No matter how often they chat with them, and no matter how well they think they know them. Tell them that people can lie about who they are, and their new friend can be a gown up instead of a 12-year-old child.

Never reveal personally identifiable information – This can be their real name, gender, age, school, phone number, or where they live. Have them use a chat pseudonym that is non-provocative and does not hint at who they really are in reality. They must also watch other people’s personal information, such as friends’ names and phone numbers.

Don’t let your kids open attachments to email messages from friends or file-sharing services without you being there to approve and scan the content for viruses.

Tell the kids that it is important not to meet online friends face to face without your knowledge. Determine the person’s true identity before permitting any meeting and if they are not sure they should ask you. Make sure such meeting happens in a public place, and accompany them.

Use programs to save writing logs – Most chat programs allow you to block a user by right-clicking on their name in your contact list and choosing the “Block” or “Ignore” feature. In the next section we will see what software’s we should use.

Use Software to Keep Track

Here is a list of software that are helpful in keeping a track of what is being viewed on your computer.


The first one in the list is OpenDNS, which can be easily downloaded from the following link – It has a free version and it allows the parents to filter all web content of all the devices that are connected to the network, this filters allow parents to select categories and add new webpages to be blocked as it can be entered in the monitoring mode, so you allow the child to navigate for the first hour and then you block all the webpages that you think are not good.

Internet Security - Spamming

Spam is a form of email which is used to send to different email accounts and in general contains advertising about any product or services. But the real problem is when they contain malwares that can damage the user’s data.

Generally, they are sent to a massive list of emails for the mail purpose that a small percentage of users might open them and respond. They are used to such treatment because they are cheap in infrastructure investment, not too much time consuming and simple.

Techniques Used by Spammers

In this section, we will discuss the different techniques used by the spammers.

  • Domain Spoofing − The spammer sends an email on behalf of a known domain so the receivers think that they know this person and open it.

  • Poisoning Filters − A filter can be poisoned by adding text with the same color of the background to reduce the scoring of the filters.

  • Directory Harvesting − In directory harvesting, spammers generate email addresses by using known email addresses from corporates or ISP (Internet Service Provider).

  • Social Engineering − Spammers send promotional emails to different users such as offering huge discounts and tricking them to fill their personal data.

  • Junk Tags − Spam Words can be hidden by including invalid HTML tags within the words.

  • Invalid words − Special characters are inserted in the spam words. For example: V!AGRA.

Anti–Spam Techniques

In this section, we will discuss various anti-spam techniques and their advantages.

  • Signature Based Content Filtering − Most anti-spam email companies use this type of filtering because it checks the received email with certain patterns after saving the message to the disk.

  • Naive Bayes Spam Filtering − Bayesian filter scans the context of the e-mail when it looks for words or character strings that will identify the e-mail as spam.

  • Black Listing RBL − This is a type of database that updates the IP address and domains based on a reputation and the system administrators who use these RBL don’t receive email from domains that are blacklisted from this RBL.

  • Sender Policy Framework − The IP address of the domain of the sender is compared with the genuine list of the IP addresses that the domain should have and if it is not same, then that email is dropped.

Chat messages are generally short in order to enable other participants to respond quickly. Thereby, feeling similar to a spoken conversation, this tool is an attractive place for cyberattacks to hack account and get data.

Risks from Chatting

Nowadays most of the chatting platforms and instant messaging websites are a big place of frauds and the risk that come from the other users are very high and are as follows −

Secure Transaction

If you or your users are using Google Chrome, you can push them to always connect securely, if the webpage supports it. Always prefer the HTTPS extension, if you are using a Mozilla Firefox there is an add-on called HTTPS Everywhere.

We should do a transaction only through webpages that we know or when they have a good reputation. So, in simple words you should visit those webpages that you trust and even though you trust, it is recommended to do the transactions through payment gateways like PayPal, so you don’t transmit bank account details to third parties.

A good resource is that gives you the rates of the websites and their reputation based on millions of users, who trust their transaction to these websites.

At the end of the month always make a physical check of your transactions if they are matching to your expenditure or not. If it is not, then it is recommended to block your payment carts or accounts immediately.

After finishing the transactions, it is recommended that you always clear history, caches and cookies. Especially if you are using another computer that is not yours.

What Should You do as a System Administrator?

As a system administrator, you should have in mind some rules that will help our customers to make a secure transaction.

  • In the first place, you should check if there is any policy compliance for the system that we are offering, like PCI, or HIPAA. Generally, these policies have security guidelines too, like hardware or software that provides access controls, integrity controls, auditing and transmission security.

  • Another thing is that a session should be limited based on time and IP. So when your user signup form is getting the account open, the system will lock out after sometime and find out if there is a possibility of any man-in-the-middle attack. The IP restriction should not allow it.

  • Make a Usage Policy for your system, so the user knows their limit and gains knowledge regarding the security.

  • Check if your system has the proper configuration for making a financial transaction. The system should have a 2-factor authentication, where a passcode or a pin number is sent to your client’s mobile phone every time an online transaction takes place and will only be approved once you confirm the purchase by entering the code. This ensures that the client is who he says he is by asking for something he knows, and something he has, like a phone.

Internet Security - Banking

In this chapter, we will deal with banking security issues related to e-banking or the so called Internet banking, and credit or debit cards based security issues.

E-banking is an electronic payment gateway which enables all the customers of a bank to do banking transactions through their computers without the need to go physically to the bank.

Normally to create an e-banking account the client has to go physically to the bank to be able to open it and authenticate it when it opens. A customer can link this account with their loans, current account and many other bank products.

How to do an e-Banking Transaction Safely?

Always enter the e-banking link by typing it yourself and not through an arriving email it can be a phishing mail. Always connect through a secure connection to the website and check if the webpage is authenticated like in the following image, where the connection is a secure Https − and the authenticity of web I have checked it through the green bar which is a certificate which means that this web is pre-authenticated.


Be cautious of any unexpected or suspicious looking pop-ups that appear during your online banking session. Think about the process you normally go through to make a payment to someone – be suspicious if it differs from the last time you used it.

Never give anyone your login details in full either by email or over the phone – your bank will never request these in this way. Check your bank statements regularly and contact your bank immediately if you find any transactions that you did not authorize.

When you send money via your online bank account, always double check the amount you are sending as well as the account number and sort code you are sending it to.

Credit Cards

Generally, these cards are issues by card providers like banks and they are connected with the client’s bank accounts and help to make payments and as this too is being used more often increasing the possibilities of frauds.

Credit Card

Credit card fraud is a theft carried out by using a credit card or any alike payment mechanism as a fake source for fraud transaction. A common type of fraud happens when an offender purchases an item online, by utilizing a credit card number that they have obtained in unethical ways.

Credit card transactions are obtained by −

  • Credit card generator site on the Internet.
  • Unethical merchant spreading credit card data of their clients.
  • Hackers can get the data from a skimmer, which is a hardware that the hackers put in the ATMs or a POS.
  • By finding discarded copies of vouchers.
  • By hacking computers where the credit card details are stored in a cache.

Credit Card Generator

The most commonly used tool for cracking credit cards is Credit Card Generator ( This Credit card generator is a command-line Python program which uses a .php script. It generates the credit card numbers that are used in the test ecommerce websites. It generates 13 and 16-digit VISA, MasterCard and Amex numbers. If installed, it can steal passwords and credit card numbers along with bank details.

Another one is called as the RockLegend’s Cool Card Generator, but there are not many details given about it.

Credit Card Fraud Detection Techniques

In this section we will discuss the various Credit Card Fraud Detection Techniques.

Pattern Detection

  • This technique marks a person as a fraudster if many orders are placed to be delivered at the same address by different credit cards.

  • If multiple orders are being sent from the same IP address.

  • If the credit card changes by a few digits.

  • If the person submits the same credit card with different expiry dates.

Fraud Screening Detection

This technique is developed by Visa and it detects fraud possibilities based on a score where 150 order variables are taken into consideration.

How to Buy in a Secure Way?

As you know, in order to navigate and purchase goods, services online the retails should always be authenticated through Digital certificates, from the security point of view this parameter is not negotiable.

Buy In Secure Way

Some of the secure online stores which have multi-seller platforms are −


It is important to mention that in these platforms there are scammers too. So in this case before buying from any seller you should see the reviews from the other buyers and what is their reputation, which are generally marked by stars.

Setup a Secure Online Shop

These standards are proprietary information standard for sites that handles payment online and uses credit cards like Visa, MasterCard, American Express, Discover, JCB and others. They would need full documentation and information to set up this Compliance. All the details can be found on their official site −

Internet Security - Certificates

Digital Certificates are a standard of security for establishing an encrypted link between a server and a client. Generally, between a mail server or a webserver, which protects data in transitions by encrypting them. A Digital Certificate is also a Digital ID or a passport which is issued by a Third Party Authority which verifies the identity of the server’s owner and not claiming a false identity.


Components of a Digital Certificate

All these following components can be found in the certificate details −

  • Serial Number − Used to uniquely identify the certificate.

  • Subject − The person, or entity identified.

  • Signature Algorithm − The algorithm used to create the signature.

  • Signature − The actual signature to verify that it came from the issuer.

  • Issuer − The entity that verified the information and issued the certificate.

  • Valid-From − The date the certificate is first valid from.

  • Valid-To − The expiration date.

  • Key-Usage − Purpose of the public key (For example: encipherment, signature, certificate signing...).

  • Public Key − The public key.

  • Thumbprint Algorithm − The algorithm used to hash the public key certificate.

  • Thumbprint − The hash itself, used as an abbreviated form of the public key certificate.

Security Certificate

Levels of Validations

In this section we will discuss the various levels of validations of an SSL (Secure Sockets Layer) Certificate. Some of the most important ones are as follows −

  • Domain Validation SSL Certificate − It validates the domain that is registered by a system administrators and they have administrator rights to approve the certificate request, this validation generally is done by email request or by a DNS record.

  • Organization Validated SSL Certificates − It validates the domain ownership and also the business information like the Official Name, City, Country, etc. This validation is done by email or DNS record entering and the certificate authority would also need some genuine documents to verify the Identity.

  • Extended Validation SSL Certificates − It validates domain ownership and organization information, plus the legal existence of the organization. It also validates that the organization is aware of the SSL certificate request and approves it. The validation requires documentation to certify the company identity plus a set of additional steps and checks. The Extended Validation SSL Certificates are generally identified with a green address bar in the browser containing the company name.

The reviews and some of the biggest digital certificate providers’ details can be found in the following link −

Internet Security - Email Security

In this chapter, we will explain the security measures that have to be taken in a mail server and on a client site.

Hardening a Mail Server

For hardening a mail server, you will need to adhere to the following steps −

Step 1. Configure mail server not to have Open Relay

It’s very important to configure your mail relay parameters to be very restrictive. All mail servers have this option, where you can specify which domains or IP addresses your mail server will relay the mails to. This parameter specifies for whom your SMTP protocol should forward the mails to. An open relay can harm you because spammers can use your mail server for spamming others, resulting in your server getting blacklisted.

Step 2. Set up SMTP authentication to control user access

SMTP Authentication forces the people who use your server to obtain permission to send mail by first supplying a username and password. This helps to prevent any open relay and abuse of your server. If configured the right way, only known accounts can use your server’s SMTP to send an email. This configuration is highly recommended when your mail server has a routed IP address.

Step 3. Limit connections to protect your server against DoS attacks

The number of connections to your SMTP server should be limited. These parameters depend on the specifications of the server hardware and it’s a nominal load per day. The main parameters used to handle connection limits include: Total number of connections, total number of simultaneous connections, and maximum connection rate. To maintain optimal values for these parameters may require refinement over time. It prevents Spam Floods and DoS Attacks that target your network infrastructure.

Step 4. Activate Reverse DNS to block bogus senders

Most of the messaging systems use DNS lookups to verify the existence of the sender’s email domain before accepting a message. A reverse lookup is also an interesting option for fighting off bogus mail senders. Once Reverse DNS Lookup is activated, your SMTP verifies that the senders IP address matches both the host and domain names that were submitted by the SMTP client in the EHLO/HELO Command. This is very valuable for blocking messages that fail the address matching test.

Step 5. Use DNSBL servers to fight incoming email abuse

One of the most important configurations for protecting your email server is to use DNS – based blacklists. Checking if the sender domain or IP is known by DNSBL servers world-wide could cut down the amount of spam received substantially. Activating this option and using a maximum number of DNSBL servers will greatly reduce the impact of unsolicited incoming email. The DNSBL servers list along with all known spammers IPs and domains for this purpose are all stored in a website, the link for this website is –

Step 6. Activate SPF to prevent spoofed sources

The Sender Policy Framework (SPF) is a method used to prevent spoofed sender ddresses. Nowadays, nearly all abusive email messages carry fake sender addresses. The SPF check ensures that the sending MTA is allowed to send mail on behalf of the sender’s domain name. When SPF is activated on your server, the sending server’s MX record (the DNS Mail Exchange record) is validated before any message transmission takes place.

Step 7. Enable SURBL to verify message content

The SURBL (Spam URI Real-time Block Lists) detects unwanted email based on invalid or malicious links within a message. Having a SURBL filter helps to protect users from malware and phishing attacks. At present, not all mail servers support SURBL. But if your messaging server does support it, activating it will increase your server security, as well as the security of your entire network since more than 50% of Internet Security threats come from email content.

Step 8. Maintain local IP blacklists to block Spammers

Having a local IP blacklist on your email server is very important for countering specific spammers who only target you. Maintenance of the list can take resources and time, but it brings real added-value. The result is a speedy and reliable way to stop unwanted Internet connections from bothering your messaging system.

Step 9. Encrypt POP3 and IMAP authentication for privacy concerns

The POP3 and IMAP connections were not originally built with safety in mind. As a result, they are often used without strong authentication. This is a big weakness since users’ passwords are transmitted in clear text through your mail server, thus making them easily accessible to hackers and people with malicious intent. The SSLTLS is the best known and the easiest way to implement strong authentication; it is widely used and considered reliable enough.

Step 10. Have at least two MX records for any failover

Having a failover configuration is very important for availability. Having one MX record is never adequate for ensuring a continuous flow of mail to a given domain, which is why it’s strongly recommended to set up at least two MXs for each domain. The first one is set as the primary, and the secondary is used if the primary goes down for any reason. This configuration is done on the DNS Zone level.

Securing Email Accounts

In this section, we will discuss how to secure the email accounts and avoid them from getting hacked.

Securing on the Client Site

The most important thing is to Create complex passwords. As there are many techniques available to crack the passwords like brute-force, dictionary attacks and password guessing.

A strong password contains −

  • 7 to 16 characters.
  • Uppercase and lowercase letters
  • Numbers
  • Special characters
Change Password

Always connect the email password with another genuine email that you have access to. So in case this email is hacked, you have the possibility to gain access again.

Install in your computer a mail antivirus, so that every email that is coming in your email client is scanned like attachments and phishing links.

Protection Control

If you are in the habit of using web access, then never open attachments with the .exe extensions.

It is recommended to use an encrypted email when communicating officially with important data. So it is better that the communication to be encrypted between the end users, a good tool for this is PGP Encryption Tool.

Internet Security - Identity Theft

In this chapter, we will discuss regarding the identity theft. What is it? How to prevent it and what measures do we need to take to prevent them?

  • Call your bank to cancel all your ATM and POS transactions.

Internet Security - Cybercrime

As in all the previous chapters, we have dealt with different ways to protect ourselves as to how we should not get into any scenario of a potential fraud. Now let us see what is our outer limit of what all we can do without making a computer crime or as it is called a cybercrime.

Types of Cybercrime

Following are some of the most prominent cybercrimes happening around the world.

Financial Cybercrime

This crime is when you utilize your skills or third party access for the main purpose to get financial profit. Like accessing an e-bank portal in an unauthorized way and make transactions, make e-commerce payments and take goods without permission.

Another widespread financial cybercrime is Credit card cloning all this has been mentioned in the previous chapters.

DoS Attack or Cyber Extortion

This type of a crime is when you threaten a company or a person that you will stop their services in case you are not “rewarded” with money to let the services run, which generally are Webserver, mail servers or other computer networks. We hear a lot of such cases on a daily basis across the world.


This is an act of terrorism committed through the use of computers. It can be a propaganda on the Internet, that there will be bomb attacks during the holidays, which can be considered as cyberterrorism.

Here are some other pointers that will make u a Cybercriminal −

  • If you produce a virus or any other type of malware that damages computers and networks around the world, for financial or non-financial profit.

  • If you make unsolicited bulk mails like spam to spread something.

  • If you make a phishing or social engineering attack you can be jailed depending on the country, you are living in.

  • If you own or create a black market for drug, weapon selling, child pornography selling.

  • If you crack or pirate a software, music or videos over the Internet you can be jailed for author copyrights.

Internet Security - Checklist

In this chapter, we will discuss the creation of a basic checklist which will keep us safe and protected from hackers and other malware at the workplace and in the home environment as well.

Basic Checklist

Here is a basic checklist of things that you should do to ensure Internet Security −

  • Account setup − There should be an appropriate policy that when an employee comes to the organization, who opens the account and what rights or privileges does the employee has, etc. What are the limits of the usage of computer resources?

  • Password Change Policy − There should be a policy where the frequency of the password change should be mentioned and the complexity of passwords that need to be used.

  • Helpdesk Procedure − There should be a proper procedure as to when someone calls the helpdesk user. They should first identify themselves based on something like a user ID or any other unique identification.

  • Access Privileges − This procedure should state how the access is granted to different parts of the network and there it should be mentioned who has authorized this access and whether they can authorize any extra access if needed.

  • Violation − There should be a policy for reporting any violations to any policy.

  • Employee Identification − They should be forced to wear an ID badge and any guest coming in should be registered if possible with a temporary or a visitor badge.

  • Privacy Policy − There should be a policy where the employees should check up to what level are they authorized to give information and when this level is passed to whom they should speak to.

  • Document Destruction − It should be checked if all the documents which are of no use any further are shred or burned.

  • Physical Restriction Access − Physical access should be protected with limited access and they should be allowed only for the employees.

  • Antivirus in Place − It is mandatory in such cases to check if the antivirus is functioning with all it functions like mail antivirus, file scanning, web scanning, etc.

  • Network Filtering − It is highly recommended to check if your network is filtered with all the accounts to the level of access of different employees. In the home environment you need to check for your parental control software, if it is in place or not.
