There are various types of computer security that a company must monitor to avoid loss of data and / or prestige. This is one of the most important issues in organizations. With so many things happening on the Internet, it becomes extremely necessary to secure the content of our network and our communications against possible problems of loss or interception of data. Computer security is the branch of information technology that deals with the protection of data on a network, its communications or an independent computer. Because all organizations are dependent on computing, security-related technology requires constant development. These are three different types of computer security.
Hardware security can be related to a device that is used to scan a system or control network traffic. The most common examples include hardware firewalls or firewalls and proxy servers. Other less common examples include Hardware Security Modules (HSM), which supply cryptographic keys for critical functions such as encryption, decryption, and authentication for various systems. Among the different types of computer security, it is the hardware systems that can provide the most robust security, and can also serve as an additional layer of security for important systems. Hardware security is also about how we can protect our physical computers from harm. To assess the security of a hardware device, it is necessary to take into account the vulnerabilities that exist since its manufacture, as well as other potential sources, such as code that runs on that hardware and the data input and output devices that are connected to it.
Software security is used to protect the software against malicious attacks by hackers and other risks, so that our software continues to function properly with these types of potential risks. This software security is necessary to provide integrity, authentication, and availability. Among the types of computer security, this field of software security is relatively new. The first books and academic classes on this subject appeared in 2001, proving that it has only been recently that developers, software architects, and computer scientists have begun to systematically study how to build secure software. Software defects have various security ramifications, such as implementation errors, buffer overflows, design defects, mishandling, etc. Too often malicious intruders can enter our systems by exploiting some of these software flaws. Applications that have Internet access also present a higher security risk. It is the most common today. Security holes in the software are common and the problem is growing. Software security takes advantage of best practices in software engineering and tries to make security think early on in the software life cycle.
Network security refers to included all activities related to the security of Internet. Specifically, these activities protect the ease of use, reliability, integrity, and security of your network and data. Effective network security addresses a variety of threats and how to prevent them from entering or spreading across a network of devices. And what are the threats to the network? Many threats to network security today spread over the Internet. The most common include:
Viruses, worms and Trojan horses
Spyware and advertising software
Zero-day attacks, also called zero-hour attacks
Denial of Service Attacks
Data interception or theft
It must be understood that there is no single solution that protects against a variety of threats. Various levels of security are required. If one fails, the others still stand. Network security is carried out through hardware and software. The software must be constantly updated to protect itself from emerging threats. A network security system usually consists of many components.
