What are the Essentials of an Effective Cybersecurity Policy?
What is a Cybersecurity Policy?
A security policy is a document outlining how to defend an organization from dangers, such as computer security threats, and address issues when they arise.
A security policy must identify all of a company's assets and all potential threats to those assets. Employees must always be informed about the company's security policies. Policies should also be updated regularly. The key assets in an organization that must be protected should be specified in a security policy. This could encompass the company's network and its physical location. A description of any potential threats to those things should also be included.
If the material is about cyber security, risks could come from within the firm, such as angry employees stealing sensitive information or launching an internal virus onto the network. A hacker from outside the firm, on the other hand, could get access to the system and cause data loss, change, or theft. Finally, computer systems may sustain physical damage.
Once the threats have been identified, the likelihood of them occurring must be calculated. A corporation must also figure out how to avoid those dangers. A few protections could include establishing particular personnel policies and tight physical and network security. There must also be a plan for what to do if a threat materializes. The company's security policy should be distributed to everyone, and the method for preserving data should be reviewed and modified regularly as new employees join.
Why Should You Have a Cybersecurity Policy?
For various reasons, having an effective cybersecurity policy is critical for businesses and organizations. Cyber-attacks are now one of the most severe threats to business continuity. Since the COVID-19 outbreak, there has been a considerable growth in remote work and rapid digitalization in formerly behind-the-times industries, giving cybercriminals a significantly bigger attack surface.
In addition, the years 2020 and 2021 demolished the myth that cyber-attacks are primarily directed at large firms, with small businesses being reasonably safe. According to Cybersecurity Magazine, small and medium-sized organizations are involved in 43 percent of cyber-attacks, with phishing being the most common attack for 30 percent of small businesses. As a result, if you own a small business, you should seriously consider implementing a cybersecurity policy.
The policy should provide clear rules for all personnel, including technical and non-technical. Ransomware attacks that begin as phishing attempts can be easily avoided with the proper training and education.
Essentials of a Cybersecurity Policy
Institutions develop information security policies for several reasons −
To create a complete information security plan.
To detect and prevent data, network, computer system, and application misuse, as well as other types of information security breaches.
To safeguard its reputation in terms of its ethical and legal obligations.
Customers' rights must be respected. Providing proper mechanisms for responding to complaints and concerns about actual or apparent policy non-compliance is one technique for reaching this goal.
An information security policy should cover all data, programs, systems, buildings, other technological infrastructure, technology users, and third parties in a specific firm.
Objectives for Information Security
An organization attempting to create a working information security policy must have well-defined security and strategic objectives. Management must agree on these goals; any existing differences in this area could jeopardize the project's success.
The most important thing for a security expert to keep in mind is that his understanding of security management techniques will enable him to include them in the documents he is tasked with drafting. This ensures completeness, quality, and applicability.
Simplifying policy language is one technique to minimize disagreements and ensure unanimity among management personnel. Ambiguous statements should be avoided, and authors should ensure that terminology and popular words are defined correctly. The policy should ideally be written in a concise and to-the-point manner. Documents with redundant text can become extensive and illegible, and having too many additional details can make full compliance difficult.
Information security is described as the safeguarding of three main objectives −
Confidentiality − Data and information assets must be kept confidential and only shared with that granted access.
Integrity − Maintaining data integrity, completeness, and accuracy, as well as keeping IT systems working.
Availability − A goal demonstrating that authorized users have access to information or a system when they need it.
Policy on Authorization and Access Control
A security policy usually follows a hierarchical structure. Unless they are given specific authority, junior employees are generally required to keep the scant information to themselves. A senior manager, on the other hand, may have sufficient authority to decide what data can be shared and with whom, meaning that they are not bound by the same information security policy standards. This means that the company's information security policy should cover every critical role and contain permission standards.
Policy refinement occurs concurrently with the definition of administrative control or authority individuals hold inside the organization.
In essence, it is a hierarchy-based delegation of control. An individual may have power over their work. A system administrator has sole authority over the system files. A user may have a pressing need to know about a specific piece of information. As a result, data must be detailed enough to give only the proper permitted access and no more. It's all about finding a delicate balance between granting access to individuals who need the data for their jobs and denying it to unauthorized parties.
Unique logins that need authentication in the form of passwords, biometrics, ID cards, tokens, and other means should be used to access the company's network and servers. All systems must be monitored to track login attempts (both successful and unsuccessful) and the exact date and time of logon and logoff.
A project manager is in charge of project files for the group to which they've been assigned. While doing so does not ensure an increase in security, it is a sensible recommendation.
Data Classification
The following is an example of how a data classification policy might organize the complete set of data −
High-risk class − Data protected by state and federal regulations (the Data Protection Act, HIPAA, FERPA), as well as financial, payroll, and personnel (privacy standards), are all covered in this high-risk category.
Confidential class − Although the data in this class is not legally protected, the data owner believes it should be protected from unauthorized disclosure.
Public class − This content can be freely disseminated in the public domain.
Data owners should specify the data classification and the specific actions that a data custodian must take to maintain the integrity of the data at that level.
Support and Operations for Data
Clauses like these can be found in this section −
General system processes accountable for data protection are regulated.
The backup of data
Data transmission
Other topics that may be included in an information security policy are −
A variety of distinct items may be included in an information security policy. These methods include virus protection and intrusion detection, incident response procedures, remote work procedures, technical guidelines, audits, employee requirements, non-compliance consequences, disciplinary actions, terminated employees, IT physical security, and more.
