Computer systems are made up of different parts, so they work like a gear. In fact, it is normal for an average user not to notice all of that detail. For this reason, there are different types of computer security. Find out more below.
What is computer security?
Computer security is a specific area within the cyber world, which is responsible for ensuring the correct operation of a system, preventing and facing all kinds of threats in that area.
In addition, it also ensures that the operation of these systems is not affected by failures or malfunctions, but can cause serious problems to its users, especially if they are companies.
Therefore, computer security is an essential requirement for any corporation that wishes to prevent attacks that could jeopardize its business. Without a doubt, it is a worthwhile investment, and later you will see why.
The computer security applied to each area
As already mentioned, computer security works on different areas of a system. This allows you to act with greater diligence and efficiency before any event, optimizing resources to solve it in the shortest possible time.
Based on the above, the types of computer security that are currently applied are the following:
1. Software security
Computer security applied and designed to provide protection to the different applications and programs that are part of the system. Therefore, it seeks to neutralize any type of external threat that may arise.
Some of the most common threats that affect software are viruses, spyware and any malware in general. To deal with this situation, cybersecurity uses different tools.
Most of them are antivirus and antispyware programs, which contain databases with the characteristics of malicious software. Which are frequently updated, detecting new malware according to the efficiency of the antivirus manufacturer and the legality of the license.
These security programs operate by performing periodic analysis on the device, although it is also possible that the user can request an analysis at any time.
Also, there are other additional programs, such as firewalls, adware blockers, antispam programs or intrusion prevention or detection devices that work based on personalized security policies according to the service of each company.
The software security application is vital for any company, especially if you consider that computer attacks are a daily issue, and at any time one can occur.
2. Computer hardware security
As we have already seen, the software requires investment for its protection, but this will not make sense if efficient security schemes are not applied to the hardware, that is, to the computing devices themselves.
The violation of the hardware can cause serious problems in its operation, and even leave them inoperative. As a result, the areas of a company that depend on computer systems can be paralyzed in a matter of seconds.
In the case of hardware, the most commonly used computer security schemes are proxy servers, as well as firewalls, which are sufficiently intelligent to interpret the context in which communication is established.
Similarly, the implementation of encryption and encryption for the protection of information that is transported through public or unsafe networks is very much in trend today.
3. Network computer security
When talking about a computer network, reference is made to different devices interconnected with each other, whose location can be the same or be different. In fact, one of the simplest ways to connected through the internet and the information exchanged.
This information is so varied and includes so many different types of data. The internet has become a virtually inexhaustible source of data. Some of them are personal data of users, documents in general, financial statements, images, among others.
Cybercriminals try to find a very attractive place to launch threats and attacks, and its main purpose is to violate some of the three fundamental pillars related to the information of a company:
- Confidentiality (information can only be accessed by authorized persons)
- Integrity (information must not be altered or corrupted by third parties)
- Availability (information always be available to be analysis)
The applications developed to execute this type of computer security include specialized software, and some of them work in the cloud, which are responsible for limiting and combating irregular situations, such as phishing, trojans, computer fraud, identity theft, etc.
Of course, these programs updated at all times, and the user must grant the necessary permissions so that they can act without limitations, as the creators of threats look for any minimum weakness to attack daily.
In this case, antivirus, proxies, firewalls, encryption also play a fundamental role. However, there are other more advanced options, such as intrusion prevention systems, and security operations centers, which facilitate the preservation of information.
Finally, it is necessary that any company that wants to stay safe from computer attacks, take into account these three types of computer security, and implement them at the same time. In that way, the vulnerabilities will be greatly reduced.
