Security is a constant thing to worry about when it comes to IT. Stealing data, hacking, malware, and an array of other threats are enough to keep the professionals worried. In this article, we will explore the basic principles and best methods that IT professionals use to ensure the safety of their systems.
Information security follows three overarching principles:
Confidentiality — This means that information can only be seen or used by people who are authorized to access it.
Integrity — This means that any modifications to the information by an unauthorized user are not possible, and changes by authorized users are tracked.
Availability — This means that the information is available when authorized users need it.
By knowing these principles, IT security experts have come up with best practices to aid businesses to ensure that their information stays safe.
Balance Safety With Convenience
Computers in an office could be fully protected if all the modems were shut down and everyone kicked out — but then they would not be of any use to anyone. This is the reason why one of the biggest challenges in IT security is obtaining a balance between resource availability and the security of the resources.
Rather than attempting to protect from all kinds of threats, most IT departments focus on defending the most vital systems first and then determining acceptable ways to shield the rest without making them useless.
Split the Users From Resources
For an information security system to work well, it is necessary to determine who is allowed to see and do particular things. Someone in accounting, for example, does not need to see all the names in a client database, but he may need to see the figures coming from sales. This means that a system administrator should assign access according to a person’s job type. This will guarantee that the chief financial officer will be able to access more data and resources than a junior accountant.
That said, rank does not mean full access. A company’s CEO may need to see more data than other people, but he does not automatically need full access to the system.
Use Independent Defenses
This is a military system as much as an IT security one. Using one excellent defense, such as authentication protocols, is only safe until someone breaches it. When several independent defenses are applied, an attacker must use several different strategies to get through them. Introducing this type of complexity does not mean you are 100 percent protected against attacks, but it does reduce the odds of a successful attack.
Plan for Failure
Planning for failure will benefit the company in the long run and allow to minimize its actual consequences should it occur. Having backup systems in place beforehand enables the IT department to monitor security measures and react quickly to a breach. If the breach is not serious, the business can keep operating on backup while the problem is solved. IT security is as much about restricting the damage from breaches as it is about preventing them.
Run Frequent Tests
Hackers are continually improving their craft, which means the security experts must evolve to keep up. IT professionals run tests, conduct risk assessments, recheck the disaster recovery plan, check the business continuity plan in case of attack, and then do it all over again.
IT security is a challenging job that demands attention to detail at the same time as it requires a higher-level awareness. However, like many tasks that seem complicated at first glance, IT security can be broken down into necessary basic steps that can simplify the process.
