Computer Security: An Overview of Defences and Security Measures

Cyber security has come a very long way since the early 1980s when it became apparent that hackers were stealing or simply destroying online data. The digital revolution has moved at a frightening pace, and as the Internet evolved, so did cyber-crime. The people tasked with protecting networks were in a constant battle to stay abreast of the hacker. Today sees leading cyber security providers employed to protect networks from hackers. Here is a brief overview of the current measures used to protect online data.

 Internet Borne Malware & Viruses

 Once a computer is connected to the Internet, it immediately becomes vulnerable to cyber-attack, and that includes private users as well as businesses. Protecting computers against web-based malware is big business. In the highly unlikely event that your device does not have anti-virus protection, this is something you need to remedy as soon as possible. Blacklisting programs are being replaced by whitelisting applications, which take up much less resources and offers better protection.

Adware

 This is one form of malicious code that hackers use to make certain advertisements appear on your computer screen. They are also designed to steal marketing information that is then sold to digital marketing agencies. This might not be a critical aspect, but it can be very annoying and also slow down your computer.

Network Defence

 Early attempts at protecting local area networks used traditional anti-virus programs, yet the modern hacker can easily penetrate a network that does not have up to date protection. If you want total cyber protection and happen to be in Australia, contact CXO Security ISO 27001 consultants, who are based in Sydney and Melbourne and can offer a comprehensive solution at a reasonable price. Firewalls are one form of network protection that are widely used with local area networks (LAN). A local cyber security provider can install such a system to protect your network.

 Employee Education

 One of the most common ways a hacker can gain access to a network is through unwitting employees who might reveal a username or set obvious passwords. Should you receive an unknown email that has an attachment, you should never open it. This is a common ploy to infect a computer with malware. Educating your employees is as important as installing anti-virus programs, as this will ensure that all workers understand the risks and adopt safer practices.

Attaining Accreditations

 When dealing with large companies and corporations, it is vital that you are accredited with PCI, DSS and ISO 27001, which indicates that your network is adequately protected. If you are unsure regarding your company’s compliance with cyber security mandates, talk to a leading cyber security provider.

An Ever-Present Threat

 Unfortunately, the threat of cybercrime is always present, regardless of what industry you are in, and to be complacent might lead to having your confidential data stolen. Every company, big or small, should have adequate cyber protection in place at all times. By training your staff on safe use practices, you can minimise the risk of becoming a cyber-crime victim.
