A lot has been said and published about how the market for unethical hackers has increased its potential due to the rising number of internet users and IoT devices. In fact, a lot of studies published in reputable print media like the Wall Street Journal indicate that there has been an alarming increase in the number of cyberattacks in the recent few years. Which is why your cybersecurity strength must match the security benchmarks set by cyber experts in order to prevent, reduce, and limit the damage caused due to malware and phishing attacks. A guide to some of those online security techniques is listed below.
- Important Password Rules
IoT devices should be protected with a strong backdoor password. Some important rules that mustn’t be ignored include the following.
- Make the password a long combination of 12-20 unique characters that must include unique symbols, letters, and numerics.
- Practice the art of using a different password for every device. Also, stop reusing old passwords for new devices.
The latest authentication technique includes MFA or multifactor authentication. Instead of one password, it involves multiple security layers that the user has to pass in order to gain access to the system. Use it wherever you can.
- Important Cybersecurity Filters
The two basic filters that guard IoT devices and prevent them from coming in direct contact of malware and viruses are firewall and antivirus. So, no matter how many systems you have in a network, every system should have a firewall and an antivirus. Also, make sure you keep debugging them.
Debugging software is important because bugs – vulnerabilities – are the sources that unethical hackers use to slip malware in a system. A few ways to remove bugs are listed below.
- Delete every unnecessary file and keep installing software updates whenever released by the manufacturers.
- Use network and system scanning tools to remove bugs from the system and the cloud.
- Run bug bounty programs to hire ethical hackers who are qualified enough to scan every code and uncover vulnerabilities – minor or serious, or both.
- Network Protection
Network protection can be divided into 2 stages. The first stage is the preparatory stage. It involves adopting techniques that will make your company attack ready if it ever happens. And the second is damage control activities that are required after the attack takes place.
The first stage includes network segmentation. It is a unique tip to create many networks, all are independent of each other. In this way you don’t have to dump the entire information in a single place; instead, you get to distribute it. So, even if hackers are able to breach the security layers of 1 network, they won’t be able to hack the entire information at once.
Next comes, having an alert cybersecurity team that can quickly identify a security breach. Remember, the sooner the breach is identified, the lesser is the damage with network segmentation in place. Also, there’s a need for a quick communication channel that can be used as an emergency channel to alert employees about the attack quickly.
