What is computer network security?

Computer network security refers to anything that is designed to protect your network against security threats. As there are now so many of these threats over the internet, it’s vital to invest in efficient security systems to target and stop them from entering your computer network, deleting important data and damaging the reputation of your business.

Computer network security threats include anything from viruses and worms, spywear and adware, denial of service attacks (DoS) and identity theft. To stop these attacks from affecting networks, businesses often deploy security software such as anti-virus software and firewalls, to block unauthorized access to their network.

Smaller businesses, however, often lack the security resources that larger companies have, meaning their computer network security isn’t as sufficient at protecting against today’s modern and more sophisticated threats.

Ransomware is a common threat to small and large business computer network security, as users are unaware that it’s on their network. Ransom attacks are a type of cryptography which installs secretly on a victim’s computer and demands a ransom payment to decrypt or unlock it.

Recently, there has been an increase in the sophistication of ransomware attacks and the data available to those who carry out the attacks. According to Beazley, ransomware attacks against businesses are set to be four times higher in 2016 compared to last year, with a growing number of hackers demanding bitcoin, a type of digital currency, rather than money.

Katherine Keefe, global head of BBR Services said: “From what we are seeing, it appears that many hackers are finding it easier to make money by holding companies to ransom for bitcoin than through selling personal data on the dark web.

“But the persistently high levels of hacking and malware attacks of all kinds are a reminder that organizations across industries, and of all sizes, need actionable plans ready to implement when a breach occurs.”

Spear Phishing also poses as a dangerous threat to computer network security, particularly for small businesses. This attack, where an email appears genuine but carry malicious software that can give hackers access to a company’s entire computer system.

Over 50% of spear phishing attacks carried out last year were against small and medium-sized enterprises (SMEs), so raising security awareness amongst employees is crucial if you want to avoid colleagues getting caught out by a spoofed email that appears to come from someone you trust.

Paul Burns, chief technology officer at TSG, said: “In an increasingly digital world, criminals have the information and the means to ensure that high profile security breaches, involving major household names, continually make the headlines. In many ways, the hackers have more opportunities to attack, given the proliferation of devices being used to access systems and data remotely – all of which can potentially leave the door open and result in vulnerabilities.

“It’s no use just thinking that it only happens to the big brands either. Very often, the hackers’ route into larger organisations is through smaller, more easily compromised, companies. Hacking has fast become a lucrative industry with a genuine recruitment drive taking place to build up teams of the most prolific cyber criminals. So, notching up as many SME security breaches as possible improves a hacker’s reputation before they are trusted with taking on larger organisations.”

With computer network security in place, you can ensure your business is not only protected against data theft and network damage, you can ensure you are meeting mandatory regulations and compliance, your employees are working productively, you reduce the risk of legal action and protect your businesses protection.
