Infographic: Cybersecurity Tips and Best Practices

 

Protecting your IT Infrastructure is very serious business these days, so how can we best safeguard against cyber threats?

With this in mind, the helpful folks from Transcosmos Information Systems put together a few best practice tips to keep your IT infrastructure secure. These include:

A secure password is that it must be at least 8 characters long Click To Tweet
Control log-in information and regularly change your passwords

The rule of thumb for a secure password is that it must be at least 8 characters long, combine uppercase and lowercase letters, and at least one number or special character. And Although it’s a bit of a hassle, it is recommended that you change your passwords regularly to keep them secure, preferably every quarter or so.

Implement two-factor authentication

Whenever possible, put in place a system that requires more than one form of authentication to grant users access. This means that in addition to a password, you can, for example connect your mobile phone to the server and get it to send you a unique code that you must enter to verify who you are.

Adding additional layers of security is recommended to keep data safe Click To Tweet
Store credentials in a secure way

The best way to avoid data breaches is securing your credentials securely through password hashing. To hash a password means to transform it into a unique value before storing it in your database. Since this is a one-way algorithm, it’s impossible to turn the hashed password back to its original form.

Always have an encrypted back-up of your data Click To Tweet
Delete users and groups you don’t use

Regularly check who has access to your servers. Are they still around? Things change and so should your permissions.

Keep your firewall and virus scanning software up-to-date Click To Tweet
Constantly scan for viruses

To catch viruses early before they have a chance to do any significant damage to your system, you should conduct regular scans and diligently update your antivirus software.

VPNs are your friends where it comes to data security Click To Tweet
Update software and operating systems

Software is a bit like bread, it’s only great when it’s fresh. You must therefore make sure you keep your infrastructure packages and operating systems updates so they’re in tip-top condition. Regular updates fixes bugs and guarantees there are not gaping holes in your system security.

Fireproof your firewall

Having a good firewall is a must for securing your server infrastructure. It provides an extra layer of protection to your system’s inbuilt security features, through which you can control all the different pieces of software or services that you need to expose to the network. Less exposure = less for hackers to get their mitts into.

SSH key authentication

SSH cryptographic keys that contain more bits of data than a typical password, making them more difficult to crack and less vulnerable to attacks. It also saves you having to remember your passwords. Win-win!

Use private networks and VPNs

Virtual Private Network (VPNs) keeps your browsing secure, and your internal communication private.

Encrypt, encrypt, encrypt ….

Encryption – the process of translating sensitive electronic data into unintelligible code – means that only those with authorized access can access and decipher your data. All the cool kids are doing it.

Install good security software

It is worth investing in packages from sources you know and trust rather than trying to cut corners, as these might provide a backdoor through which hackers can access your systems.

Find your vulnerable spots before hackers do Click To Tweet
Test your vulnerabilities

Regular network vulnerability scanning can help you identify weaknesses in your server and address issues before hackers get to them.

If you can afford it, hire a professional to help keep your commercial IT systems secure Click To Tweet
Keep secure and encrypted backups

Your data may well get lost or corrupted at some point, and if that happens, you definitely want to have a plan B to allow you to quickly get back on track.

SSH keys also mean you don't have to remember loads of passwords Click To Tweet
Get a Pro to have your back

In this increasingly complex security landscape, it pays for companies to have an IT expert on their side to keep on top of security.
