The security is governed by different aspects and it is crucial to know the different types to avoid computer attacks that could jeopardize the data or prestige of companies. Every day more, the Internet is the channel through which viruses are introduced in organizations that can cost millions. To avoid this kind of attacks, the first thing to do is to know the different types of computer security there are.
Network computer security
Do you hear viruses, worms or hackers? Identity theft or spyware? All of them are failures in network computer security and can be fought with antivirus and antispyware, firewalls or virtual private networks or VPN.
Network security aims to protect the computer network from all threats that may enter or spread through a network of devices. At the same time you should minimize the maintenance of it.
The most common protection strategies used by the administrator of networked computer systems are to use different levels of security, so that while working at the same time, there is always one working. They include hardware and software security. A good network security system minimizes network maintenance and improves security at all levels.
Computer hardware security
Firewalls or hardware firewalls and so-called proxy servers are elements that control network traffic and are part of hardware IT security. They are in charge of offering a more powerful and secure security and at the same time they protect other systems such as networks, for example. HSMs, or hardware security modules, protect encryption or authentication for different systems using cryptographic keys.
But computer hardware security goes further, and also deals with the security of computer equipment. For example, to know if there are security errors from your configuration or the code that executes the hardware, as well as the input and output devices that you have. Everything influences hardware security and must be taken into account to avoid unwanted intruders.
Software computer security
Software security or the construction of secure software is something relatively new. Developers work to build software that is increasingly secure from the moment one.
The objective is to protect the software from frequent errors related to security such as implementation errors, design flaws, buffer overflow … These software defects can serve as an input for viruses or hackers. Therefore, working on secure software since its creation is crucial for its security.
