The Ultimate Guide to Countering Common Network Security Threats

We now live in a world dominated by new and innovative technologies and the internet. Initially intended to help businesses and individuals for their move to digitalisation, new technologies and innovations have also paved the way for new threats. A huge number of organisations are reporting breaches in IT security caused by viruses, malware, and hacking. In fact, according to a Government Security Breach Survey, 74% of organisations are reporting security breaches.

This is a significant increase from 2013 and 2014. Although the nature of a “threat” varies from business to business, you can counter them all by implementing various IT security protocols intended to protect sensitive business data. A research by Symantec even found that if businesses had a simple cyber security plan in place, they could have protected 82% of their data, which was either lost or stolen. Look at this guide below to protect your business from common network security threats:

Spear Phishing

Spear phishing or identity theft is one of the most common security threats to any start up or established organisation. Employees/users/managers typically receive an email asking for sensitive information like username and password. Since the email appears genuine to all employees at an organisation, it is easy for fooling people and forcing them to give access to a company’s entire security system. This makes it a major network security threat.

A recent stat from Symantec found that more than 52.4% of spear phishing attacks carried out in the December of 2015 were against medium and small-sized enterprises. This is mainly because they are easy targets. To protect your business, it is imperative that you educate your employees to look out for any warnings signs of suspicious emails or implement SPAM filtering. Also, make it essential for only responding to sensitive information face-to-face (not even on the phone).

Unsecured Wireless Access Points

Unless you have been living under a rock, it is likely that your business uses wireless devices daily for accessing the internet and local area network. While there is no harm in using wireless networking, it has also significantly increased the security risks to your network. If intruders are physically present within your office premises, they can connect to your network and release viruses, malware or attempt to hack your servers.

This can result in the stealing of sensitive information, which can prove incredibly costly for your business (especially if you are dealing with money of clients, customers, etc).  To prevent this from happening, you need to set up proper network security with the help of IT Support London. You can implement various protocols like changing default passwords, encrypting information, and boosting security of your wireless network by limiting access to unprivileged users. Monitoring your traffic is a good way to ensure protection against any network attack.

Malicious code

Due to its ability of causing vulnerabilities in the system (like stolen passwords and deleted files) and secretly installing on computers, Malicious Code exists as one of the biggest network security threats to a business. According to Kaspersky Lab, hackers can steam employee and customer information to gain financially, as not all antivirus protection and protocols can block this threat.

Malicious code is not like malware. It is present in your website script, causing damaging effects just like Trojan Horses and Worms. To prevent this from happening, you need to update your IT security system, while installing Proactive Warning Services like anti-virus and anti-spyware programmes on all computers in your business. Otherwise, chances are you may lose all important business data.

USB and External Devices

According to a research conducted by Security Research Labs in 2014, it was revealed that USBs and other external devices have the capability of being reprogrammed for stealing the contents of any PC. They can even pretend to be an active network card, gaining the ability of changing your computer’s domain name to redirect your traffic secretly (tracking all online and local area network searches). Make it a strict rule to limit the use of USBs and external devices in your organisation to counter this problem.

As you can see, protecting your business from network security threats can get tricky, especially when you have to look out for so much. It is a good option to hire professional IT support services to help you come up with appropriate plans and use advanced software for protecting your network and IT information at all costs.
