7 Basic Theoretical Principles of IT Security

Security is a frequent concern when it comes to information technology. Data theft, hacking, malware, and a host of other threats are enough to keep any IT professional up at night.Bentley ProjectWise In this article, we'll cover the basic principles and best practices that IT professionals use to secure their systems.

Goals of Information Security

Information security follows three general principles.

Confidentiality: This means that information can only be seen or used by those who are authorized to access it.

Integrity: This means that any changes made to information by unauthorized users are impossible (or at least detectable) and that changes made by authorized users are traceable.

Availability: this means that the information can be accessed by authorized administrative users when they develop a need for it.

So with these higher-level principles in mind,Bentley BIM IT security experts have come up with best practices to help organizations ensure that their information remains secure.

IT Security Best Practices

There are many best practices in IT security that are specific to certain industries or organizations,BIM Viewer but some of them are broadly applicable.

Balancing Protection

An office computer can be completely protected if all the modems are compromised and everyone is kicked out of the room, but it's of no use to anyone. That's why one of the biggest challenges in IT security is balancing resource availability with resource confidentiality and integrity.

Rather than protecting against a wide range of threats, the vast majority of IT departments focus on protecting the most important systems and then finding acceptable ways to protect other systems without rendering them useless. Some lower priority systems may be candidates for automated analysis, so the most important systems remain the focus.

Splitting Users and Resources

For student information to work for security management system research, it must know who is allowed to see and do specific things. For example, an accounting professional does not need to see all the business names in a client database, but he may develop a need to see sales data. This means that a system administrator will need to assign access rights based on the different types of work he or she personally does, and they may just need to get further refinement of these problematic restrictions based on social organization separation. This will ensure that the CFO ideally has access to more data and resources than a junior accountant.

That said, ranking does not mean full access. The CEO of a company may need to see more data than others, but he does not automatically have full access to the system. This leads to the next question.

Assigning Minimum Privileges

Individuals should be assigned the minimum privileges needed to fulfill their responsibilities. If an individual's responsibilities change, so do the privileges. Assigning least privilege reduces the chances of Joe walking away from the design with all the marketing data.

Use independent defenses

This is a military principle, just like IT security. Using a very good defense, such as an authentication protocol, is best only until someone violates it. When multiple independent defenses are used, the attacker must employ many different tactics to achieve this. Introducing this complexity does not provide a 100% defensive attack, but it reduces the chances of a successful attack.

Failure

A planned program will help reduce its practical consequences. After backing up the system first, the IT department can continuously monitor security measures and respond to breaches. If the breach is not serious, the business or organization can continue the backup operation after the issue is resolved. It's security also limits the damage of breaches because it is designed to prevent them.

Record, Record, Record

Ideally, a security management system can never be compromised, but when an information security technology breach occurs, the incident should be documented. In fact, IT employees work to routinely carry out as much logging as possible, even if the breach doesn't china between occurrences. Sometimes, in fact, the cause analysis of the breach is not there obviously, so an important is to keep track of the data. Data from breaches will ultimately help us improve the instructional system and prevent future attacks - even if it doesn't initially make research sense.

Run frequent tests

Hackers are constantly improving their techniques, which means that information security must evolve to keep up with them. it professionals run tests, perform risk assessments, reread disaster recovery plans, examine business continuity plans that have been compromised, and then repeat it again for it.
