Computer Network Security

Cybersecurity, computer security or information security is basically the protection of networks and computer systems against external threats, such as malicious attack, intentional intrusions or damage of their electronic data, hardware or software, and from the intentional disruption or misuse of their services. These are very significant activities which will lead to the security, protection and preservation of all our data and assets. Cybersecurity is also a branch of information security whose prime aim is to secure networks from any attack and to maintain the integrity and confidentiality of information. All the top corporations, government agencies, small, medium, and even smaller organizations and even end-users are investing on this branch due to its importance and effect on the entire information system.

In the field of cybersecurity, we can talk about many different issues and concerns, including DDoS (damage, disruption, and theft) that result from malicious Internet activity. There are several well-known malware that attacks the computers and Internet of an organization and causes severe damage. A brief description of some of these is mentioned below. Cyber criminals are using various kinds of programs to spread viruses, malware, and harmful codes among the computer network. Some of them are the Remote Access Virus, Lockheart virus, and the Mycorubytomator.

The common goal of cyber threats is to exploit the vulnerabilities of a computer system. A few of these are described below: Remote Access Virus, password theft, file system corruption, security feature bypass, key logger, and application vulnerability. On the other hand, there are several major types of cyber threats that have been recently discovered and reported. Each has different features and objectives, including:

A wide variety of software applications are used for carrying out a variety of cyber attacks and are capable of doing harm to the systems. The most common and dangerous of these tools are those that use remote control and web exploits. Several of these types of attacks include the Remote Code Execution (RCE) and the Execute Virus (E Io). Some other major types of cyber attacks include: data capture, data theft, denial of service, system file corruption, security flaw, and denial of service due to spam.

Cybersecurity incidents can be prevented if proper measures are taken by companies. Companies must take preventive steps in order to minimize the occurrence and severity of the various computer system threats. There are several information security threats that involve the use of malware. The most common and serious form is malware attack, which can destroy data or cause other problems.

One of the main objectives of the malware attack is to access and occupy the computer system of a victim with the use of Trojans and other malware. In some cases, the attack could also be classified as a Distributed Denial Of Service (DDoS) attack. DDoS attacks usually occur when attackers to flood a network using a large amount of network traffic in order to overload a particular website. In this attack, the attacker uses a distributed protocol to send spoofed packets that could lead to confusion on the part of the target server. Another serious type of malware attack is phishing attack. This involves sending spoofed e-mails to collect personal or financial information.
