Cybersecurity, computer network or information security is basically the protection of computer networks and systems from the intentional damage or theft of their electronic information, hardware, software or even their physical merchandise. Computer security specialists to monitor, diagnose and mitigate the risks posed by network vulnerabilities, and help businesses and organizations safeguard their most valuable assets. One of the more common forms of cyber crime is targeted web hacking which can compromise a business website. Cybersecurity measures are implemented to reduce the risk of attack, detect and prevent any further penetration and to protect information and systems from being compromised. There are several categories under which cyber security systems are classified according to severity. The classification system is mostly used for the benefit of users and operators to ensure that their information is protected in the face of cyber attacks.
Various studies indicate that nearly one in every ten computers in the United States are infected with spyware, adware or viruses. These malware programs, if allowed to gain access to a network, can cause serious problems for legitimate users of that network, particularly if those users do not practice adequate preventative measures. Hackers use various tools and techniques to gain unauthorized access into a computer system. Among the most common techniques used by hackers are Remote Access, Broken Pipe, and ActiveX Control, which are all ways that an unauthorized person can gain unauthorized access to a computer system without using any physical access methods such as a password. To defend against these attacks and protect against hackers, network security experts have developed various techniques and applications, most often known as antivirus or firewall applications, that help to prevent unauthorized access to a computer system.
Even so, security threats can take new forms and pose problems that have never been tackled before. It is, therefore, important that network security professionals continually improve their skills to stay updated with newer technology and the potential problems they may bring up. Certifications for the same are at the disposal of anyone who is seriously considering to expand their skill-set to include current cybersecurity practices. Starting with a brief look at practice ISC exams free to be taken by anyone may act as a bridge between current knowledge and further education in information security.
In order to counter the unauthorized access and other vulnerabilities that can contribute to the vulnerability of a network, the most important form of cyber security protection is physical security measures. Physical security measures may include the installation of advanced firewall programs that prevent hackers from accessing the source code of the application and accessing the system files and folders. In some cases, physical security measures may also include securing the physical location of a computer system, such as securing it in a secured building or server room.
Unfortunately, the cost of securing networks and computers can be high. For this reason, many smaller organizations and businesses do not invest in these types of security measures. Even when they do install effective antivirus programs, they often do not prioritize patching their systems for security vulnerabilities. Without patching, an already compromised system becomes even more vulnerable. Furthermore, many of the smaller businesses and organizations that do not have an IT department may lack the necessary expertise or resources to adequately secure their systems.
A major obstacle facing the cybersecurity industry is penetration of internet technology infrastructure into the corporate network. Many organizations today rely on third-party consultants to help them secure their networks. While some companies attempt to self-install iot devices, the reality is that it is typically more cost effective to deploy to devices through an internet provider. Regardless of whether an organization chooses to self-install or procure iot devices from a third party, the ultimate goal is to secure the older CTI (computer systems) and network equipment through layers of firewalls, virtualization and other measures.
However, even with the most stringent measures, cyber attacks are likely to occur. Attackers may exploit a vulnerability in a CTI, or they may simply choose to send an unauthorized employee through an infected USB drive. As a result, even though a majority of IT professionals are aware of the potential threat of these attacks, they are usually unable to protect the personal information stored on their computer systems. Only someone who is skilled in exploiting and attacking computer systems can protect corporate and personal information by preventing the attacks against the critical infrastructure of a business.
Today, several providers of software and cloud services are attempting to address the issue of cyber security by developing industry standard protocols and addressing the issues of unsecured network connections. Some of these industry-standard protocols are industry certified to help provide a higher level of network security for organizations. The Cloud Security Alliance (CSA), a membership organization made up of the largest and most prestigious cloud computing providers, has been instrumental in developing a number of industry standard application security features. One such feature is the encryption of data transport over the internet. Encryption is a complex process that requires the simultaneous deployment of numerous security measures, including authentication, encryption of sensitive data at the data-incident detection level, management of private networks and ensuring that no one can access the victim’s data in the event of a data loss.
These highly complicated tasks are only the beginning of addressing the issues of cyber attacks. Enterprises must also be aware of and learn to protect themselves against security breaches that affect their daily operations. The easiest way to do this is by using existing firewall and antivirus software that have been specifically designed to prevent attacks against cloud servers. A Cloud Security Alliance member is required to demonstrate that their products are regularly updated to address new threats and vulnerabilities. With these tools and a good understanding of what they can and cannot protect, any enterprise can ensure its systems are well protected from all forms of cyber attacks.
