What is Cyber Hygiene? Understanding Its Impact on Data Protection

There’s no doubt about it: technology has become an integral part of our lives. It’s interwoven in our work and personal lives, and for the most part, it benefits us greatly.

However, technology isn’t without its risks. Vast amounts of data are collected and stored each second. Keeping this data safe is a significant concern, and good cyber hygiene is one way to minimize those risks.

Just as personal hygiene involves routine steps, cyber hygiene is a series of measures you can take to ensure the health and security of your computer systems, networks, and data. Poor cyber hygiene can lead to data loss and catastrophic breaches and cost businesses an average of  4.45 million USD per breach. The problems aren’t just financial, though. Poor data hygiene can also have legal implications and affect your company’s reputation. In this article, we’ll explore how cyber hygiene impacts data protection and how good cyber hygiene can help protect you from cyberattacks.

What Are The Fundamentals of Cyber Hygiene?

To implement cyber hygiene effectively, businesses must be familiar with the basic principles and key components of cyber hygiene. The fundamentals of cyber hygiene are as follows:

Basic Principles

• Regular software updates and patch management: Software updates usually contain patches to tackle newly discovered vulnerabilities and flaws. 
• Password management: This may include regular changes and strong, complex passwords. You should never use personal information that can be easily guessed, such as your date of birth or children’s names, nor should you use the same password for multiple devices/programs. A password manager can help you keep different passwords safe if you’re worried about forgetting them.
• Regular backups and secure data storage: All data should be backed up to an external area such as a hard drive or the cloud. This will help you recover your database in the case of a data breach.

Key Components

• Network security measures: These include firewalls to prevent outside entities from accessing data and intrusion detection systems to raise the alarm and block the threat quickly.
• Malware protection: This includes antivirus software and anti-malware tools that can detect, remove, and prevent malware from all connected devices when updated regularly.
• Secure configuration and hardening of devices and systems: This means removing software that is no longer needed, reconfiguring settings to boost protection, and disabling unused services. This can reduce the number of entry points for attackers.

What Are the Benefits of Maintaining Good Cyber Hygiene?

Taking steps to protect your customer’s data is a compelling reason to implement good cyber hygiene, but there are several other benefits as well: 

Prevention of Data Breaches

In the past few years, many businesses have reported some kind of cybersecurity breach, and this figure has increased for larger companies. Most data breaches come from bad actors who find and exploit security weaknesses that occur primarily because of poor cyber hygiene protocol. 

Enhanced Data Integrity and Confidentiality

Cyber hygiene also maintains data accuracy, integrity, and privacy. Not only does this help keep customers' data safe, but it also helps with compliance. Companies can face hefty penalties and fines for failing to meet statutory requirements.

Improved System Performance and Reliability

Regular maintenance plays a crucial part in ensuring system efficiency. You can benefit from a more reliable IT environment by updating software regularly and running the latest operating systems. Moreover, maintained systems run more effectively as the risk of fragmentation is reduced. 

What Is the Impact of Cyber Hygiene on Data Protection?

Good cyber hygiene significantly improves data protection by reducing the risk of security breaches and data theft, ensuring that data remains safe and private. More specifically, robust cyber hygiene enhances data protection in the following ways:

Regulatory Compliance

GDPR (General Data Protection Regulation) has strict rules around data protection. Following cyber hygiene best practices helps businesses meet strict regulatory requirements. This is because cyber hygiene allows businesses to implement the best security measures.

Another critical regulation is HIPAA (Health Insurance Portability and Accountability Act). HIPAA-regulated businesses will need strong cyber hygiene, including real-time logs for critical access points to prove who is accessing data and when.

Risk Management

Losing data can be catastrophic for a business. Proper cyber hygiene practices should include data loss prevention and help identify and mitigate cyber risks. This ensures businesses take the most effective measures to protect their digital assets.

Strengthening Cyber Defense

Cyber hygiene fortifies organizational defenses against cyber threats. Because threats can be internal or external, taking a multi-pronged approach is essential to identify and prevent attacks and shield your valuable data in the best possible way. 

Good cyber hygiene is the first line of defense against threats. If you don’t keep up with simple things like updating software or training employees to spot suspicious emails, your data could be compromised.

Best Practices for Implementing Cyber Hygiene

Did you know that something as simple as neglecting to update your software can open doors to cybercriminals, much like leaving your front door unlocked invites thieves? What steps are you taking to ensure your digital presence isn't vulnerable to easily preventable risks?

When implementing cyber hygiene, engaging in best practices will go a long way in optimizing data protection. Here are practical steps you can take to ensure strong cyber hygiene:

Develop a Cyber Hygiene Policy

A cyber hygiene policy sets out and communicates the practices and procedures everyone within the organization should follow. The policy should be stored in a central location and be accessible for all relevant parties to access. With data security at the forefront, the fundamental principles of the policy should include:

• Details of all network assets, such as hardware, software, and applications.
• Timeframes for routine cyber hygiene practices like password changes and updates for hardware and software.
• The use of strong, unique passwords. These should include numbers and special characters and not be easy to guess. This means steering clear of personal information and using an original password for every online account.
• Details of how new installs should be managed and documented.Details of access rights to limit users to a specific level of data access to suit their role.Details on data backup procedures in the event of a breach or malfunction.
• Consider telephone security risks, too. If you serve customers in the eastern Ohio area, for example, a local number with a 330 area code, could give them peace of mind.

Once the policy is in place and specific time frames are set, it must be communicated effectively so everyone knows their responsibilities.

Employee Training and Awareness

Many data breaches are down to employee error. With 57% of users admitting to writing their passwords on a sticky note, it’s easy to see why. Effective training can ensure staff understand the importance of data protection and cyber security. Some simple steps to create effective staff awareness include:

• Make following protocol a priority. Employees need to be aware of their responsibilities for data protection and understand how data breaches occur. Even when software updates automatically, it’s a good idea to ensure staff know who to report issues or glitches to should they happen.
• Staff must know how to access the cyber hygiene policy. Documents should be shared with all employees, and training sessions should be held to discuss the key points. This helps to check everyone is on the same page.
• Train staff on the threats and explain their accountability.

Regular Audits and Assessments

Regular security audits and assessments can help you identify vulnerabilities in your systems. Because technology changes so quickly, being able to identify threats means you can adapt accordingly. Regular audits and assessments also highlight the effectiveness of your security measures.

Tools and Technologies to Aid in Cyber Hygiene

Using effective cybersecurity tools can help you keep your data safe. Choosing the right tools to meet your needs can take a little bit of planning, but some tools to include in your portfolio include:

• Automated Patch Management Systems: This helps to ensure updates are done in a set time frame and aren’t missed. Automated patch management systems also help keep cybersecurity experts on top of other tasks.
• Password Managers and Multi-Factor Authentication: Password managers store all a user’s passwords securely, helping avoid the problem of stolen passwords. MFA adds an extra layer of security to logins. Users must provide additional verification, such as a one-time code, facial or fingerprint recognition, and password.
• Backup Solutions and Disaster Recovery Plans: The 3-2-1 backup strategy protects multiple copies of your data from various threats. Holding three copies of your data is generally enough to recover from a failure and ensure business continuity. Keeping some copies off-site protects data against physical threats such as fire or flooding.
• Cloud Email Security Solutions: Over 90% of modern cyberattacks and breaches begin with phishing emails, making robust email security an essential part of strong cyber hygiene. A comprehensive cloud email security solution can detect and block all malicious mail before it reaches the inbox, thus preventing most attacks and breaches.
