Cybersecurity is critical for businesses both small and large. We know that hackers and malware attacks make the news on a regular basis. But many companies still neglect the network security aspects of their business. These are four of the most common cybersecurity mistakes that businesses make. And these are the steps you can take to avoid them.
Mistake #1: Underestimating the Human Element
People are very susceptible to the lure of links. An email arrives in an employee’s email inbox from what seems to be one of the company’s software providers. It urges the receiver to click on the link to apply an important update to their software. Or to login and change their password because of a recent security vulnerability that was discovered. One click, and a drive-by download installs malware making it possible for a hacker to access the company’s network. Even the best web filters and email filters have trouble keeping up with all the new attack variants.
Employees need to learn to view the email messages they receive with a critical eye. As well as how to browse the web safely and think carefully before they click on a link. They are often the last line of defense against hackers, and the weakest link in a company’s security chain. Money invested in training your employees about cybersecurity is money well spent.
Mistake #2: Mistakenly Allowing Former Employees to Continue to Access Company Data
Too many companies are not careful enough about system access after an employee leaves the company. Some examples of forgotten details include the following:
- Invalidating all of the employee’s account passwords, including workstation and network passwords
- Removing the employee from access lists
- Retrieving all backup data sources the employee may have used, including items such as external hard drives or thumb drives
- Retrieving all work-related devices, including cell phones, tablets, laptops, etc.
- Either deactivating or removing the employee’s accounts for things such as email, laptops, desktops, and servers
When an employee leaves voluntarily or is fired, every company needs a security protocol. To make sure they do not still have access to company systems. Failure to have a protocol puts the company at risk. As well as leading to HIPAA violations if personal health information is involved.
Mistake #3: Failing to Upgrade and Update Software and Operating Systems
Refusing to upgrade to newer versions of software and hardware may seem like the most economical thing to do. However from a security standard standpoint it is very risky. Additionally security measures are included in updates, which may be based on weaknesses discovered in previous versions.
Another issue with outdated software is that it may no longer be supported by the vendor. Meaning that security vulnerabilities go unresolved. Outdated software is commonly exploited by hackers, who often keep track of when applications are no longer supported. Using unsupported software can allow them to gain entry to your network and critical data. The same can be said of outdated hardware, which also can have serious vulnerabilities. A good example of exploiting hardware weaknesses is the VPNFilter malware, which originally targeted older model routers.
Updates are just as important, as they often provide critical patches for recently discovered bugs. Procrastinating when it comes to updates, as annoying and needlessly time-consuming as they seem, leaves your system unnecessarily open to malicious attacks. And this advice is equally applicable when it comes to firmware, too.
Mistake #4: Using Weak Passwords
Let’s start off by looking at some of the worst password practices out there:
- Writing passwords down where someone can find them, including writing them on paper or storing them in a spreadsheet on your computer
- Using passwords that are less than 12 characters long
- Only using all lower-case or upper-case letters, and rarely (if ever) using numbers or symbols
- Allowing browsers to save your passwords
- Sharing passwords with fellow employees
- Rarely change passwords
- Use the default password for hardware and programs
- Using the same password (or very similar passwords) for multiple accounts
- Using something easy for someone to figure out, like birthdays, anniversaries, pop culture references, last names, and pet names
Did any of that look familiar? It turns out that most companies aren’t as careful as they should be about passwords, which can seriously compromise their cybersecurity. Experts recommend not only enforcing rigorous password standards. But to include multi-factor authentication as an extra security measure. And, educating employees on password standards and why they are so important.
You might have noticed that three out of the four common mistakes discussed above directly involve employees. All employees need to be informed about what they can do to support the cybersecurity of the company. How important of a role they play as the last line of defense against hackers. And never underestimate the importance of applying all software and firmware updates, or letting your software become outdated.
