Why you need to lock and update your computer

In cybersecurity, small habits can make a big impact. Of course, two of the most effective yet overlooked habits are locking your computer when you step away and updating your software when new versions are available. These actions protect both your personal data and your company’s systems. Having updates installed is crucial to protect against vulnerabilities that could allow hackers to install malware on your computer.

This article explains why these habits matter, how they help prevent cyberattacks, and how to integrate them into your daily routine.

Cybersecurity starts with you

Many people believe that cybersecurity is solely the responsibility of the IT department. In reality, your own digital behavior plays a critical role in keeping systems secure and mitigating risks associated with a cyber attack. Each employee has access to sensitive information, which makes individual responsibility essential.

The IT team handles technical solutions, but you are responsible for:

  • Completing cybersecurity awareness training

  • Locking your computer when you leave it unattended

  • Installing system and software updates as soon as they become available

Implementing these practices in your daily routine is crucial. These simple actions reduce the risk of data breaches and malware infections significantly.

Protecting your computer from unauthorized access

Leaving your computer unlocked, even for a brief moment, can pose a serious risk to your organization’s sensitive data and overall cybersecurity. Locking your computer every time you leave your desk is a simple but powerful habit that helps prevent unauthorized access and potential data breaches.

While the IT department implements technical safeguards, cybersecurity is a shared responsibility. Employees play a vital role in protecting company devices by adopting secure habits. An unattended computer can become an easy target for hackers, who may install malware, access confidential information, or compromise the entire network. This highlights the importance of regular security training and awareness.

To help protect your computer from unauthorized access:

  • Use a strong, unique password to prevent unauthorized logins.

  • Make sure to regularly install updates for your operating system and software to strengthen security and benefit from the newest protection tools.

  • Enable a password-protected screen saver that activates after a short period of inactivity.

  • Set up a hot corner or shortcut key to quickly lock your screen when you step away.

  • Avoid using public Wi-Fi for work-related tasks unless you’re using a secure VPN connection. Public Wi-Fi networks typically lack proper security, which makes it easier for cybercriminals to access private information sent over the connection. Explore the risks of public networks and how to stay protected.

  • Do not use unsecured personal devices for accessing company systems or data.

  • Participate in regular security awareness training to learn how to recognize phishing attempts and suspicious behavior.

  • Report any unusual activity immediately to your IT or security team.

By adopting these simple but effective habits, employees strengthen the organization’s overall security posture. At the same time, the IT department can support these efforts by enforcing screen timeout policies, deploying endpoint protection, and providing ongoing training.

Protecting your computer requires a combination of secure behavior, technical safeguards, and continuous awareness. Ongoing cybersecurity training and phishing simulations are essential to keep both individuals and organizations one step ahead of evolving threats.

In today’s threat landscape, these actions are not optional — they are essential.

Why locking your computer is essential

Leaving your computer unlocked, even briefly, can expose your data to serious threats. Think of an unlocked computer as an open door to hackers and other unauthorized individuals. Always remember to log off when finished for the day to protect against unauthorized access.

Locking the desktop is crucial to prevent unauthorized access when you are away from your computer.

Here are the main reasons why you should always lock your computer:

  • Your personal and work-related files should not be accessed by others

  • Colleagues may unintentionally delete or modify important documents

  • Confidential emails and information must remain private

  • Malicious actors could install malware if they gain physical access to your device

Even in trusted environments like an open office, your device should never be left unattended without locking it.

How to quickly lock your screen:

  • On Windows, press Windows key + L

  • On Mac, press Control + Command + Q

Make it a habit to lock your computer every time you leave your desk to protect sensitive information.

Encouraging users to develop good security habits is essential in maintaining a secure environment.

The importance of updating your computer

Keeping your operating system and software up to date is a vital part of cybersecurity. It is crucial to take updates into account as they are often released to fix vulnerabilities that hackers actively seek to exploit.

Here are five key reasons to update your computer regularly:

  1. Updates close security gaps in the system

  2. New features and improvements are added

  3. Performance and speed are enhanced

  4. Compatibility with modern tools and applications is ensured

  5. Your data is better protected against emerging threats

Given the dynamic nature of technology, regular updates are essential to maintain security and efficiency.

Delaying updates increases the time hackers have to exploit known flaws, which puts both personal and company data at risk.

What is software patching?

Patching refers to the process of fixing software bugs and vulnerabilities through updates. When a security flaw is identified, developers create a patch to resolve it and prevent exploitation.

In the realm of cybersecurity, the concept of law plays a crucial role. Hackers operate on both sides of the law, exploiting security vulnerabilities in operating systems, which underscores the importance of regular software updates to protect personal and company data.

An outdated system is more vulnerable to malware, ransomware, and unauthorized access. If your computer is running slowly or behaving unusually, it could be a sign that an update is overdue or that your system has been compromised. To better understand these threats, learn how malware operates and explore how ransomware can lock down your files.

Installing updates regularly keeps your software stable, efficient, and secure. Security programs can help enforce these updates, ensuring that your system remains protected.

Build better cybersecurity habits

Strong cybersecurity starts with individual actions. By locking your screen when you leave your desk and keeping your system updated, you contribute to a safer work environment and reduce the risk of cyber incidents.

Provide your contact information for updates and newsletters to stay connected and receive personalized information.

Make these practices part of your routine:

  • Lock your computer whenever you step away

  • Install updates as soon as they become available

  • Monitor your system’s performance and stay alert to changes

These habits may seem simple, but they are powerful tools in achieving success in preventing unauthorized access, data loss, and cyberattacks.
