How to Protect Yourself Against Data Security Threats

Updated on June 15, 2023

More people worldwide are under constant threats of data insecurity now more than ever. The threats have grown both in number and in complexity. Data security breaches have led to losing financial assets, authenticity, and trust in victim companies and individuals. Given the growth in sophistication of the threats, the importance of protecting against such cannot be insisted enough. Here are some tips to protect yourself against major data security threats.

Encrypt All Your Data

Sensitive data at rest or in transit should be encrypted at every moment so that cybercriminals cannot read it if they were to access it. Ensure that your network is also encrypted when sending sensitive data online. Data encryption converts all the data into a secret code, which you can only read when you input the right access code.

Get Antivirus Software for Your Devices

Antivirus software helps detect and protect your devices from malware. If you are likely to click on random links online or you use a shared computer, an antivirus is a must-have tool. The most recent operating systems, like Microsoft Windows, already have built-in antivirus software. You can still consider investing in a reputable antivirus program to strengthen your protection. 

There is also freely available and legitimate software that you can get from well-known and trusted companies. However, be careful when choosing an antivirus for your computer. Hackers often advertise fake free antivirus programs that download viruses to your computer instead of helping detect and eliminate them.

Update Apps Regularly

Cybercriminals use the vulnerabilities in software to steal your data. Hence, all your applications and programs should be up to date with all the new features and security update patches. Every time a new version of your software is released, the version includes security updates to protect you against emerging data security threats and to fix security bugs that may have been undetected in the older version.

If you think you might forget to install the updates, you can use automatic software updates so that you do not have to do it manually. Remember also to keep your web browser plugins updated.

Use Complex Log-In Credentials

Passwords are the first line of defense against data security threats. Having different account passwords is important to ensure your protection against cyber-attacks. Create strong, unique, and secure credentials when setting up an account. Use reasonably complex character combinations and regularly change them, especially for accounts with sensitive data. Some sites have the option of two-factor authentication for every sign-in attempt to discourage cybercrime. A second layer of protection is an automatic boost of security.

Regularly Back Up Your Data

If a cyber-attack occurs, you should have all your data backed up, so it can be easily restored. Data loss, especially in organizations, can result in huge financial losses. For example, the famous ransomware attack on Toyota’s supplier delayed the production of over 13,000 cars. Data should be backed up regularly through cloud storage or an external hard drive. If you opt to use an external storage device, keep it away from your workplace and encrypt it to regulate access to the data. On the other hand, backing up data in the cloud also uses encryption before data is transferred and stored.

Use Secure Wifi Connections

Using safe and secure Wi-Fi connections on all your devices is very important. However, if you have to use public networks, be very careful not to handle sensitive transactions. Free Wi-Fi and hotspots are notorious for cybercriminals. Such connections make it easy for them to access and manipulate data on your device. It also puts you at risk of hackers checking to see what passwords you use to access your online accounts. However, using a virtual private network (VPN) for free Wi-Fi can help. Also, avoid shopping online or checking sensitive information on your device when you are not sure about the security of the network.

Get Internet Protection

Every internet activity flows through your service provider’s server. It is critical for your data security that you trust your internet provider. Internet protection encompasses the internet, browser, and website security as it applies to other applications or operating systems. A robust firewall is critical in ensuring your internet access is protected. It acts as a barrier between your secure internet connections and other unauthorized users and networks. Firewalls also block unwanted traffic between your computer and other devices and help prevent malicious software from infecting your computer.

Secure Your Endpoints

This involves the implementation of endpoint security controls, such as virus detection software. Endpoint security helps manage the top cyber risks depending on their ability to be detected. Some of the best cloud-delivered endpoint protection and detection responses are across multi-domain control points. It stops threats and blocks malware by detecting, containing, and immediately remediating data security threats that escape the device’s front-line defenses.

Assess Behavioral Patterns

Monitor your device for intrusion, misuse, or out-of-line habits and trends on your data. When you detect such patterns, you must monitor your employees or anyone directly accessing your data. Use intrusion detectors to monitor your devices for any unusual network activity. When the system detects potential security threats, it sends out an alarm or generates alerts depending on the cyber security threat detected.

Implement Privileged Access Management Protocols

Access or identity management is a framework of policies, software, and technology a business or individual implements. The goal is to ensure that only the right users can access technology resources and data. IAM systems allow companies to assign single digital users and access privileges for each user to prevent data breaches. It also delivers risk-aware, end-to-end multifactor authentication and single sign-on access options to ensure that data is protected against security threats.


Your sensitive data should be safeguarded to prevent breaches. However, protecting against data security threats goes beyond taking the above measures. It also involves responding to breaches promptly and effectively mitigating any consequences that may have come up.
