Security has become a significant concern for businesses. The recent introduction of social engineering is getting increasingly complex for companies to thwart cybercriminals. As such, IT companies are scrambling to implement security protocols to prevent unauthorized access from hackers. They also seek to protect their sensitive data from falling in the wrong hands. Unfortunately, not all businesses are as careful with their security strategies as they should be. Below are some of the most common security mistakes made by companies.
Blocking All Unused Ports and Protocols With Firewalls
This is a common mistake made by companies that believe they can stay safe by blocking all ports and protocols that are not in use. Unfortunately, blocking unused ports and protocols is impractical and lax on security standards. This is a bad idea because blocking new ports and protocols will prohibit legitimate applications from accessing the network. Users will not be able to access their applications. This can cause an uproar. Keeping your firewall rules updated is essential. Blocking unused ports and protocols is not practical as companies will have to keep updating their firewall rules to stay protected. Hackers can still get through when you block ports before the vulnerability is discovered and patched regardless of your firewall rules.
Failing to Use a Web Application Firewall
In addition to a firewall installed on your inbound and outbound traffic. A web application firewall acts as an additional layer of security. It inspects all information that passes through it. Web application firewalls look at the HTTP headers and URL queries. They determine whether the traffic is malicious or not. This allows legitimate connections to go through while blocking the malicious ones. The WAFs can detect potential threats before they happen. This includes SQL injection and cross-site scripting.
Uninstalling Websites and Apps After the End-Of-Life Date
All software must have an end-of-life date, beyond which it is no longer supported. The end-of-life date is the last day a company will receive support for any issues during use. However, many companies fail to uninstall outdated applications or websites after the end-of-life date has passed. This can lead to negligent security issues. Outdated apps and websites can be discovered through Google searches and exploited by hackers. You need to make sure that you remove any outdated applications or websites immediately after the end-of-life date.
Leaving the Backdoor Open
A backdoor is a method of gaining access to a system or network without the knowledge of its owner. In some cases, hackers can use it to gain access to sensitive data. Unfortunately, many businesses do not install effective security measures such as a firewall or antivirus software on their computers. This allows hackers to gain access through backdoors. Some web applications have backdoors that hackers can exploit to bypass security measures and gain access to sensitive information on your computer. To prevent this from happening, you need to make sure you close unused backdoors that may exist on your computer before hackers exploit them.
Using the Same Password for Everything
It is not uncommon for businesses to use the same password on their business sites as they do on their sites and applications. Unfortunately, this can be disastrous if malicious hackers steal the password. If your website is hacked, hackers can use malicious code to access your password if you use the same password for all of your accounts. If you have a lot of sensitive information on the Internet, it is good to use unique passwords for every account. It is also important to avoid sharing one single password between multiple accounts. This is highly insecure and could lead to you revealing sensitive information about yourself.
In today’s digital age, companies need to be as vigilant and proactive as possible regarding online security. Cyberattacks have become more and more prevalent. Businesses must do everything to protect themselves from these criminal operations.
