Phishing and malware are the two biggest cyber security concerns that need to be addressed if you want to reduce the risk of a security breach. Unethical Hackers have been extorting money from users on the web by stealing their personal information and encrypting the data on the IoT devices and decrypting it only in the exchange of a ransom. The easiest means to launch malware or phishing attacks are emails. Google filter usually detects fishy emails, but sophistication creates a bundle of problems. Hackers have become so advanced that it’s difficult even for filters to keep the inbox 100% spam-free. Which is why it’s necessary that you adopt as many cyber hygiene habits as possible to reduce such security threats.
It’s not easy to identify a phishing email when it’s addressed to an individual user with very specific and accurate information – spear phishing. Besides, the front of the URLs isn’t responsible for the page you’d be redirected to. It’s the last part that’s responsible. Since most people are unaware of these details, they end up opening malware corrupted links and files on their systems. Therefore, awareness is the key. Hold seminars for your employees and teach them a few anti-phishing tricks.
- Always inspect the header and subject line of the emails from unsolicited email Ids.
- Use URL scanning websites before opening links on the system.
- Network Segmentation
Network segmentation is a wonderful technique that can limit malware damage. How?
When you create multiple independent networks and store bits of information in those isolated networks, malware in one system cannot spread from network to network directly. It is curtailed to the network of the infected system only. As a result, it’s easier for the cybersecurity team to find out the source of infection. Though, some important factors that determine the success ratio of network segmentation are listed below.
- If the response is late, hackers will send the same authentic-looking email to employees on different networks. Unaware of the attack, employees might click on the links, leading to malware spread. Thus, early detection is necessary to limit malware.
- A faster means of communication is extremely important. Even if the malware is detected early but there’s no way to inform employees – that includes remote workers too – the chances of malware spread will be substantial.
- An efficient cybersecurity team with skilled individuals is another requirement. You can hire ethical hackers with specific skill sets. Remember, the company will suffer only as much damage for as long as the malware remains in the network. Having skilled professionals who can troubleshoot early will reduce the extent of damage manifolds.
