A recent analysis of the most damaging software attacks revealed that many cybersecurity guides overlook critical protections, leaving systems exposed to threats. However, developers can adopt practical steps to enhance their defenses significantly. Here’s a breakdown of these 10 essential practices, explained in plain language.
Limit access based on roles
Not everyone needs access to every part of a system. Granting access based on an individual’s role can mitigate damage in case an account is compromised. The concept is simple: everyone should have access only to the resources and tools necessary for their specific responsibilities.
Monitor your systems consistently
Keep a close eye on your software, servers, and tools. Continuous monitoring helps detect unusual activity early. This way, when unexpected changes occur, such as a sudden drop in account activity or unauthorized access to sensitive data, you can catch them immediately.
Control communication at key connection points
Your application doesn’t exist in a vacuum. It often connects with outside systems or tools. Monitoring these key connection points, particularly where internal and external systems meet, can help block potential threats and intrusions.
Track changes to system settings
When attackers gain access, they often change settings to create backdoors or weaken defenses. By logging and reviewing changes to your system configurations, you can spot unusual activity and investigate it quickly.
Require secure logins for everyone
Weak login practices are one of the easiest ways for hackers to get in a system. Strong passwords and multifactor authentication should be the rule for all users, including part-time team members or contractors.
Update software components when fixes are available
Most applications rely on external software packages or tools that must be updated regularly, particularly when critical security patches are released. Failing to install these updates leaves apps vulnerable to known security risks, significantly increasing their exposure to potential threats.
Consider the ways your software might be attacked
Before an attacker finds a weak spot, try to find it yourself. Often called threat modeling, this process helps you understand how your app might be targeted so you can take preventive action.
Share information only with those who need it
Reduce the amount of sensitive data handled within your system, and make sure it’s only used when absolutely necessary. When you minimize its exposure and restrict its usage to essential situations, you lower the risk of data being compromised or mishandled.
Protect data stored in your systems
Always encrypt and securely store your data. Should hackers manage to steal your encrypted data, it will remain indecipherable and significantly less valuable to them.
Prioritize fixing the biggest risks first
Not every issue is equally urgent. Focus on fixing the most critical problems first, especially those that could be easily exploited. By prioritizing based on risk, you can make the best use of your team’s time and effort.
