Cybersecurity Mistakes to Learn from 2021

No matter how safe you think your system’s cybersecurity is, there’s always some chance of errors occurring. In some cases, even the tiniest mistakes, when unaddressed properly, could lead to severe vulnerability in your system. If your business heavily depends on technology, understanding the various types of cyberattacks is vital because it can help you get prepared for what you may encounter. At the same time, it is also critical to comprehend how widespread cyber-attacks have become and how probable they are to occur. To help you build a robust cybersecurity in 2022, here are some cybersecurity mistakes to learn from 2021.

Why Does This Happen?

Majority of software vulnerabilities are the result of a mistake that has gone unnoticed. Thus, a knowledgeable cybersecurity specialist should warn you whenever a cybersecurity issue occurs, since it is truly difficult to give 100% guarantee that no cyberattack will take place. Cybercriminals are highly trained specialists who are able to coordinate extremely tricky attacks. Serious efforts need to be taken to prevent these attacks before they bring any damage to your business. Such an incident can leave your software and its users vulnerable to all manner of cyber-attack such as SQL injection, DDoS, Ransomware, Malware, and many more. 

Mistakes to Learn From

Preventing cyberattacks such as Malware, DDoS, and others begins with testing your program for new or pre-existing vulnerabilities and taking precautions not to expose oneself during or after the development process. To get a better grasp on this, here are some of the most-common cybersecurity mistakes.

1 . Lack of Penetration Testing

Penetration testing is one of the most effective techniques to tackle possible threats and is a critical part of overall cybersecurity. This is a method of testing the security of your program before an attacker has an opportunity to do so. Unfortunately, many developers often overlook this process. Security flaws are ones that might result in real-world losses of cardholder information, IP addresses, personal records, health information, ransomware, or other malicious activities. Without this simple but effective method, your software could be exposed to significant threats in the future, since you are leaving it up to chance whether or not you have a vulnerability in your program. 

Penetration testing allows your business or development team to identify security vulnerabilities, compliance gaps, and imitate the possible real-world implications of a large-scale data breach.  To do this, testers utilize systems that replicate hacking scenarios in order to uncover and modify security flaws. This method may also be used to train information security teams in dealing with cyberattacks and testing their reaction time. Similarly, security budgets may be allocated, and sensitive data can be protected by more robust security methods.

2 . Lack of Third Party Code Testing

The third-party code is generally utilized to execute critical operations for the program you’re creating. Because this will have an impact on several aspects of your final construction, it is necessary that this part of cybersecurity be protected. This may come as a surprise to some, but engineers rarely create software from scratch. Instead, they create software that is a mash-up of existing code, tools, and other software that has been acquired or is open source. Third-party code or software may have flaws that the original creator or future users failed to identify or just overlooked. Furthermore, many developers are unable to precisely identify the third-party parts they are utilizing or if they have been security inspected.

So, what are the options? To start with, it is critical to understand what code is being employed. Second, it is much more important to ensure that it has been tested and proven to be dependable. Limiting yourself to third-party features that have previously been proven to be reliable will go a long way toward ensuring your program has comparable levels of solid security. This may appear to be unnecessary effort, but software may live or die based on its security record. For example, WordPress add-ons are frequently left removed due to negative ratings. Therefore, it is crucial to ensure that your code is safe and that your reputation is solid.

3 . Active Backdoor Accounts & Poor Security

Another cybersecurity mistake is using backdoor accounts during testing, then forgetting they exist and ignoring to remove them. Although it is unlikely that anybody will discover it, if they do, it will be a whole different story. If this occurs, you may find yourself in a world of cyber-attack suffering. Even big enterprises fall into this hole. Cisco, for example, discovered that they had left backdoor accounts accessible, allowing attackers root access to susceptible devices. In fact, these were massive security loopholes that anybody might have exploited.

After testing any program, you want to ensure that any backdoor accounts are retired and any login credentials are erased when you are done. This is relatively simple to perform, but it is frequently overlooked. If it stays ignored, it can seriously provide attackers with an additional channel of attack in the future.

4 . Leaving Data Unsecured

Data security is likely the most serious security issue in the programming industry. Insecure, unencrypted data processing can take various forms, but it is always a source of frustration for programmers. Sensitive data cannot be protected unless it is encrypted both in transit and at rest. Anything less makes it extremely susceptible. This might include passwords, usernames, webcam access, financial information, and much more. Some of these are costly to consumers, while others severely infringe on their privacy. A lack of encryption, for example, is undoubtedly one of the most common mistakes that a programmer may make.

Encrypting data is not a 100% guarantee that your cybersecurity is risk-free. You must test your encryption methods to ensure that they are completely installed and capable of withstanding all types of brute-force cybersecurity threats. This includes utilizing cutting-edge data encryption. Similarly, strong encryption is useless if the programming that covers it is troubled with vulnerabilities that hackers could exploit. Fundamentally, installing a secure software firewall to prevent unwanted access to your computer systems and encrypting your network with a VPN service are the very least steps you can do to protect your cybersecurity. Encryption, on the other hand, must be handled seriously; not as a one-size-fits-all security mechanism, but as one that is as thoroughly tested as your program itself.

Considering cybercrime is on the rise and more complex types of attack are being created, releasing software which has not been adequately tested is no longer a viable option. Proper data security must be prioritized, since keeping data unprotected can lead to massive data breaches in the future, which would hurt both your clients and the reputation of your business.
