Data breaches aren’t limited to big companies. Even the most well-funded IT department can slip up and put critical information at risk. The average cost of a breach tops $9.44 million in the U.S. The good news is that a few basic strategies can make all the difference in averting catastrophe. Here are seven ways to keep your IT systems secure.
1. Remember That Knowledge Is Power
Many threats are shockingly simplistic. Clicking an unfamiliar link in an email can install malware on a computer. People can be conned into giving out personal information over the phone. The most vital task for IT professionals is to know these tricks better than criminals do. Equally important is spreading this knowledge to everyone willing to learn. Studies show that most breaches are due to simple human error.
Remember to prioritize learning about rapidly developing applications and software tools. Many business apps use low code programming to make them simpler for inexperienced users to build, so consider taking a low code course to expand your knowledge of unique security challenges associated with this and other emerging technologies.
2. Use Secure Connections
It’s common for employees in modern companies to take a lax approach to internet privacy. Workers will assume that company IT departments deploy powerful enough antivirus countermeasures that no concern is warranted. This attitude can be dangerous. The use of public unsecured WiFi connections opens the door to intrusion software. Caution everyone to use password-protected WiFi when working remotely. It’s good to encourage the use of virtual private network (VPN) functions to keep IP addresses hidden. Any extra layers of privacy protection put a buffer between your network and danger.
3. Backup All Data
IBM’s Cost of a Data Breach Report found that incidents cost around $164 per record compromised. Much of this cost includes reputation repair and damage recovery. Backing up your most vital information makes the recovery process smoother. Storing the most sensitive information (including client records) securely offline from the outset can be a smart preventative measure. With options ranging from encrypted discs to flash drives, backing up data securely is a quick and relatively inexpensive way to boost security.
4. Ensure Rigorous Security at All Endpoints
Remote work is making offices more flexible. The same trend can be a nightmare for IT professionals. The number and diversity of devices are bad enough. The variability of security protocols is more troubling. Good endpoint security emphasizes standardization. All devices linked to your network should be equipped with the same level of antivirus protection. Everyone should be using passcodes and other common-sense security measures. Be sure that there are no weak links in your network’s chain.
5. Adopt a Zero-Trust Architecture
These days, attacks can come from all directions. It’s impossible to gauge the intent of everyone who accesses your network. For this reason, it’s best to assume the worst of new users. This idea is central to the zero-trust approach. Verification standards should be kept rigorous. Use multi-factor authentication (MFA) measures where possible. In addition, access levels should be structured to limit the lateral movement of users. In the digital age, trust has to be earned.
6. Break Up Data Silos
Whether you’re performing IT functions for a company or public organization, different departments can have conflicting agendas. Breakdowns in interdepartmental communication can result in data being hoarded, mishandled, or even forgotten. This phenomenon is called a “data silo.” Silos typically arise from conflicted leadership teams and poor management. Coordinate with management to find new ways to integrate data to centralize storage and protection.
7. Never Leave Facilities Unsecured
It pays for IT departments to be on the same page as physical security teams. One of the more common hacker strategies is called “dumpster diving.” Criminals comb through trash looking for discarded passwords, old invoices, and records containing personal identity information. Always shred documents before discarding them, and prioritize security around waste disposals and points of entry.
Small mistakes can cause harm. Thankfully, small steps to mitigate damage can work wonders. Keep these tips in mind when boosting the security of your IT infrastructure.
