What is IT security? It’s a topic that covers a number of issues that affect the overall safety and security of a computer network. Often, by the name itself, it covers all aspects of computer safety and security which includes computer architecture, firewall, anti-virus, intrusion detection and prevention, etc.
A lot of people use the terms interchangeably when discussing IT security. Computer security, cyber security or digital security is the protection of networks and computer systems from the damage or theft of either their hardware data, or even electronic data, and from the interruption or misdirection of their services. As there are a lot of terms that are commonly used in this industry, it is important to differentiate them from one another. The three basic areas of this industry are Network Security, Enterprise Protection, and Information Technology Security. Each of these three different topics has its own unique definition and the use of the term may not be appropriate for certain circumstances.
Network security is protecting a computer system from unauthorized access. Generally, network security software or firewall is used in order to prevent hackers from directly accessing a computer system. This prevents them from gaining access to a computer or server, which can be very risky if the hacker knows how to bypass the measures that are set up on the server. Examples of the security software that can be used include anti-virus, firewalls and anti-spyware.
Another area is data security, which is used to ensure the privacy and integrity of corporate information. Data security software checks for threats, such as viruses, worms, Trojans, spyware and malware. Once the threats are detected, the appropriate solution is then set to tackle the problem. Data security software can be used to address threats from both outside and inside a company. Examples of data security software include anti-virus, anti-spyware and integrity management programs.
Besides protecting the IT infrastructure, a company should also take a look at their IT assets. These are all parts of the IT system that are used regularly and are usually hard to replace or repair. An important aspect of the assets of a company is their confidential nature. Confidential assets include access to sensitive documents, databases and networks. The most common types of confidential IT assets are servers, workstations, laptops and other peripheral devices.
An important aspect of a company’s IT security policy is creating an environment that will allow an unauthorized person to access the information or data that should be confidential. This is achieved by ensuring that the IT infrastructure is always operating in the correct state. When an IT system is not running in the correct state, an unauthorized person can gain unauthorized access to the information or data that is stored on the system. Therefore, to make sure that the system is always operating in the correct state, the company should create a test lab that allows for the testing and inspection of servers, workstations, laptops and other IT related equipment.
To protect company confidential information from being stolen or compromised, the company should have a security plan in place. The plan will involve the prevention of unauthorized access to the systems through testing, inspection and reporting of any irregularities. Information security refers to the prevention of unauthorized access to electronic data in storage.
Information integrity refers to the ability of the IT infrastructure to ensure that an unauthorized person or group of people cannot gain access to data that is stored. Information integrity also refers to the quality of service provided to clients. A company should maintain a good service level so that they receive maximum benefits from their IT investments. IT security policy involves the assessment of a company’s risk exposure and management of that risk. IT security policies will determine how to minimize risk and the actions to take when threats emerge.
