Techopedia Staff May 19, Source: Security is a constant worry when it comes to information technology. Data thefthackingmalware and a host of other threats are enough to keep any IT professional up at night.

The Goal of Information Security Information security follows three overarching principles: This means that information is only being seen or used by people who are authorized to access it.

This means that any changes to the information by an unauthorized user are impossible or at least detectedand changes by authorized users are tracked. This means that the information is accessible when authorized users need it. So, armed with these higher-level principles, IT security specialists have come up with best practices to help organizations ensure that their information stays safe.

IT Security Best Practices There are many best practices in IT security that are specific to certain industries or businesses, but some apply broadly. This is why one of the biggest challenges in IT security is finding a balance between resource availability and the confidentiality and integrity of the resources.

Rather than trying to protect against all kinds of threats, most IT departments focus on insulating the most vital systems first and then finding acceptable ways to protect the rest without making them useless.

Some of the lower-priority systems may be candidates for automated analysis, so that the most important systems remain the focus. Split Up the Users and Resources For an information security system to work, it must know who is allowed to see and do particular things.

This will ensure that the chief financial officer will ideally be able to access more data and resources than a junior accountant. This brings us to the next point. Assign Minimum Privileges An individual should be assigned the minimum privileges needed to carry out his or her responsibilities. Assigning minimum privileges reduces the chances that Joe from design will walk out the door with all the marketing data.

Using one really good defense, such as authentication protocols, is only good until someone breaches it. When several independent defenses are employed, an attacker must use several different strategies to get through them.

Plan for Failure Planning for failure will help minimize its actual consequences should it occur. Having backup systems in place beforehand allows the IT department to constantly monitor security measures and react quickly to a breach. If the breach is not serious, the business or organization can keep operating on backup while the problem is addressed.

IT security is as much about limiting the damage from breaches as it is about preventing them.

Record, Record, Record Ideally, a security system will never be breached, but when a security breach does take place, the event should be recorded. Run Frequent Tests Hackers are constantly improving their craft, which means information security must evolve to keep up. IT professionals run tests, conduct risk assessments, reread the disaster recovery plancheck the business continuity plan in case of attack, and then do it all over again.

Think hackers are all bad? The Takeaway IT security is a challenging job that requires attention to detail at the same time as it demands a higher-level awareness.

However, like many tasks that seem complex at first glance, IT security can be broken down in to basic steps that can simplify the process.

From defining complex tech jargon in our dictionary, to exploring the latest trend in our articles or providing in-depth coverage of a topic in our tutorials, our goal is to help you better understand technology - and, we hope, make better decisions as a result.Information security is concerned with the confidentiality, integrity, and availability of information.

From these three 'pillars', the following principles must be applied when implementing and maintaining an information system. In his January column, leading software security expert Gary McGraw offers his 13 principles for sound enterprise system security design. Many of his design principles are adapted from those.

Defining Security Principles. To understand how to manage an information security program, you must understand the basic principles.

These principles are the building blocks, or primitives, to being able to determine why information assets need protection. Principles of Computer Security: CompTIA Security+ and Beyond [With CDROM] (Official Comptia Guide) [Wm.
