Difference between Internal and External Penetration Testing
Penetration testing is a cybersecurity procedure during which a team of specialists checks networks, software, hardware, applications, etc., for security weaknesses. Essentially, penetration testing is ethical hacking performed for the benefit of the company that orders the test on its own systems.In some fields such as financial services, healthcare, and government system access, penetration testing is required by regulators, while it is voluntary in others. Penetration testing is an important information security technique that should be included in an organization's governance framework in the face of constantly shifting threats.Network penetration testing, also known as 'infrastructure penetration testing', can be conducted ...
Read MoreHow does real-time response mitigate the risks of cyber threats?
The Importance of Real-Time Threat InformationWhen it comes to cybersecurity, timing is everything, which is why combating cybercrime proactively rather than reactively is crucial.Fresh, focused, and actionable information is gathered from internal and external sources, as well as automated and human-generated sources, including real-time threat intelligence. Consider forums on the dark web, social media, analyst reports, and hacktivism sites.This real-time threat information gathered from different sources may be used to assist IT professionals such as CISOs, fraud managers, and SOC managers, among others, in responding to attacks faster, repelling them more effectively and strengthening their systems against future threats. In ...
Read MoreWhat is Data Loss Prevention (DLP)? (Types, Importance, How Does It Work?
Data Loss Prevention (DLP) refers to the cybersecurity measures and safeguards that individuals and corporations employ to prevent and identify data loss on their networks, whether as a consequence of data breaches, malware attacks, or other means. While ordinary Internet users should be interested in DLP to safeguard their personal data and devices, corporations are investing in DLP to secure their data in accordance with government laws.DLP technologies perform both content inspection and contextual analysis of data sent via messaging applications like email and instant messaging, in motion over the network, in use on a managed endpoint device, and at ...
Read MoreWhat is Cyber Terrorism? How is it different from Hacktivism?
The US Federal Bureau of Investigation defines "cyberterrorism" as a deliberate attack on a computer system, computer data, programs, or other material with the express purpose of inflicting violence on clandestine operatives and subnational groups.Cyberterrorism is defined as the use of computer technology to commit acts of terrorism. We must first distinguish between "crime" and "terrorism" because they are similar in certain ways, and both attack societies' capacity to maintain internal order.Terrorism is "political, " whereas crime is "personal".Individuals commit crimes for various reasons, the most significant of which are personal gains and the desire to mentally and/or physically injure ...
Read MoreWhat is Domain Generation Algorithm (DGA)? (How It Works, How to Detect?)
Cyber-attackers utilize a Domain Generation Algorithm (DGA) to generate new domain names and IP addresses for malware's command and control servers. It is practically hard for security professionals to detect and limit the attack since it is carried out in a seemingly random manner."Conficker A and B", a family of worms that created 250 domain names every day in the beginning, promoted the tactic. Starting with "Conficker C", the virus would produce 50, 000 domain names each day and contact 500 of them, providing an infected workstation a 1% chance of getting updated every day if the malware controllers only ...
Read MoreWhat is Stuxnet Worm? (Importance, How Does It Work, How to Prevent)
Stuxnet is a computer worm that was created to attack Iran's nuclear facilities but has since mutated and spread to other industrial and energy-generating facilities.The original Stuxnet malware attack was aimed at PLCs, which are used to automate machine processes. It was the first known virus capable of crippling hardware when it was discovered in 2010. It was identified to have been manufactured by the US National Security Agency, the CIA, and Israeli intelligence, generating a frenzy of media attention.Stuxnet works by targeting machines and networks that use the Microsoft Windows operating system, then looking for Siemens Step7 software using ...
Read MoreWhat are Parameter Tampering Cyber Attacks?
Parameter Tampering is a straightforward assault against an application's business logic. This attack takes advantage of how a lot of programmers use hidden or fixed fields as the only security protection for specific actions (such as a hidden tag in a form or a parameter in a URL). Attackers can readily change these settings to get around security systems that rely on them.Web Parameter TamperingWeb parameter tampering flaws are perhaps the most commonly understood danger. Tampering with parameters should be possible on a regular basis with −Query strings in URLsHeaders in HTTPFields in a formCookiesThe Web Parameter Tampering attack is ...
Read MoreWhat are the Seven Foundational Principles of Privacy by Design?
In general, privacy refers to the right to be left alone and the freedom from interruption or intrusion. The right to control how your personal information is gathered and utilized is known as information privacy.The concept of responsible use and protection of information falls under the domain of privacy, which is partially overlapped with security. Body integrity can also be a sort of privacy. Many countries' privacy laws, and in some cases, constitutions, include the right not to be exposed to unjustified intrusions by the government, corporations, or individuals.With the growth of the Internet, the incidence of social bots has ...
Read MoreWhat is a Boot Sector Virus?
A BIOS (Basic Input Output System) is a program that allows a computer's microprocessor to start the computer when you switch it on. It also controls data flow between the operating system of the computer and associated devices such as the hard disc, video adapter, keyboard, mouse, and printer.Similarly, files need to be loaded before the operating system loads. BIOS also has a piece of software or code called Bootstrap. Bootstrap is a set of instructions that instruct your computer to load the operating system. These instructions are hard-coded with the BIOS once you have installed the operating system.What is ...
Read MoreWhat are Anti-Spoofing Techniques? How are They Used to Stop DDoS Attacks?
What is Spoofing?Spoofing is a type of online assault in which cyber attackers alter the address or source of a packet to make it appear as if it came from a trustworthy source. Enterprises set up routers, firewalls, and gateways to identify fake or spoofed packets. These devices are responsible for inspecting each incoming packet and verifying its origins. Anti-spoofing is a method of detecting packets with incorrect addresses.Spoofing usually consists of two parts: the spoof itself such as a forged email or website, and the social engineering component, which encourages the victims to act. A successful spoofing assault can ...
