Let’s talk about IT security. Unlike physical security—where locks, alarms, and cameras are visible—IT security works behind the scenes, and it’s easy to underestimate. However, just like physical security, it should be treated as a spectrum, and you should always aim for a minimum standard where the risk becomes unacceptable. Here are simple measures you can take to ensure your business is at that level.
1. Passwords: Create Strong, Unique Keys to Your Systems
When it comes to passwords, there’s a lot of debate about how often to change them. Some argue that frequent changes encourage easier choices, while others believe it reduces the risk of brute-force attacks. Regardless, complex passwords are non-negotiable. Here’s how to make them strong:
-
Use a mix of symbols, uppercase letters, and numbers.
-
Make up random words or phrases—don’t rely on common substitutions like “@” for “a” or “3” for “e”.
-
Never reuse passwords. A password manager can help you store and generate complex passwords.
2. Multi-Factor Authentication: A Small Effort for Big Protection
Multi-factor authentication (MFA) can be a bit of a hassle, requiring a mobile code or additional security questions to log in. But it’s worth it! Think of it like locking the door on your way out instead of just pulling it shut. MFA adds an essential layer of security to your accounts and prevents unauthorized access.
3. Admin Access: Restrict It to Reduce Risk
Does everyone in your company have admin access? Granting too many people the ability to modify settings or download files can increase risk. Best practice suggests that you restrict admin access as much as possible to reduce potential threats.
4. Backups: Never Skip This Critical Step
Backups should be part of your ongoing security plan. Here’s what you need to know:
-
Schedule backups regularly.
-
Store backups in multiple locations (including off-site or in the cloud).
-
Monitor and test backups to ensure they work properly.
-
Encrypt your backups to protect sensitive information.
5. Antivirus: Choose Wisely and Keep It Updated
Not all antivirus software is created equal. It’s crucial to choose the right product for your needs and make sure it’s:
-
Regularly updated to protect against evolving threats.
-
Monitored so prompt action can be taken if needed.
6. Firewall: Guard Your Network Like a Security Guard
A firewall acts as a filter, monitoring data entering and leaving your network or computer. It’s like a security guard deciding who can come in and who must stay out. Ensure you have the right firewall in place, whether it’s hardware or software.
7. Patching: Don’t Ignore Software Updates
Patching is one of the most critical aspects of IT security. Software vendors release patches as soon as they discover vulnerabilities. The WannaCry ransomware attack in 2017 could have been much less impactful if machines had been kept up to date.
