Why Do We Need Cybersecurity Best Practices?

Cybersecurity best practices are essential for organizations of all sizes to protect themselves against cyber threats. Some of the main reasons why we need cybersecurity best practices include:

• To prevent cyber attacks:
  Cybersecurity best practices are designed to help organizations protect themselves against a wide range of cyber threats, including viruses, malware, phishing, and hacking. By implementing best practices, organizations can reduce their risk of experiencing a cyber attack.

• To protect sensitive information:
  Cybersecurity best practices are designed to help organizations protect sensitive information such as personal data, financial information, and confidential business information. By implementing best practices, organizations can help ensure that sensitive information is kept confidential and secure.

• Compliance:
  Many laws and regulations, such as HIPAA and the GDPR, require organizations to implement certain cybersecurity best practices. By following best practices, organizations can ensure that they are in compliance with these regulations and avoid penalties for non-compliance.

• Maintaining Business Continuity:
  Cyber attacks can cause significant disruptions to an organization's operations, resulting in loss of revenue, damage to reputation, and in some cases even legal liabilities. By implementing cybersecurity best practices, organizations can help minimize the impact of cyber-attacks and maintain their business continuity.

Top CyberSecurity Best Practices for Security Professionals

As cyber-attacks continue to increase in frequency and sophistication, security professionals need to stay vigilant and take proactive measures to protect their organizations from potential threats. Here are some of the Top Cybersecurity best practices for security professionals.

• Regular patching of vulnerable components:
  One of the most effective ways to protect against cyber threats is to ensure that all software and systems are up to date with the latest patches and security updates. Many security vulnerabilities are discovered and patched by software developers, but if systems are not kept up to date, these vulnerabilities can be exploited by attackers. It is important to establish a regular schedule for applying updates and patches and to ensure that all systems and applications are included in this process.

• Use of strong credentials and passwords:
  Another important aspect of cyber security is the use of strong and unique passwords. Passwords are often the first line of defense against cyber attacks, and weak or easily guessed passwords can leave systems vulnerable to compromise. Brute-force attacks and dictionary attacks are some of the attacks that can be used to guess weak passwords. Security professionals should encourage their employees to use strong, unique passwords that are at least $12-15$ characters long and include a mix of letters, numbers, and special characters. Multi-factor authentication (MFA) should be enabled wherever possible to provide an additional layer of security.

• Implement a firewall:
  A firewall is a network security system that monitors and controls the inbound and outbound network traffic based on preconfigured security rules. Firewalls can help to protect systems and networks from unauthorized and unintended access, and can also be used to prohibit unwanted traffic, such as malware and malicious attacks. Security professionals should ensure that a firewall is in place and that it is properly configured to only allow necessary inbound and outbound traffic.

• Regularly back up important data:
  Regularly backing up important data to an off-site location is an essential aspect of cyber security. One can even use cloud providers such as AWS, Azure, and GCP for regular backups across different zones on the globe. In the event of a cyber-attack or other disaster, having a recent backup can make it possible to quickly restore systems and data to their previous state. Security professionals should establish a regular schedule for data backups and ensure that they are tested and verified to ensure they are usable in the event of an incident.

• Security Awareness Training within the organization:
  Employees can be the weakest link in an organization's cyber security defenses. Security professionals must train their employees on security best practices and make sure they understand the importance of keeping company information secure. This can include training on topics such as how to recognize phishing emails, how to create and maintain strong passwords, and how to handle sensitive data properly.

• Limit access to sensitive information:
  Limiting access to sensitive information to only those who need it is an important security practice for organizations because it helps to reduce the risk of unauthorized access, misuse, or disclosure of sensitive information. By limiting access to sensitive information, organizations can ensure that only authorized individuals have access to the information. This helps to protect the confidentiality of the data and prevent unauthorized access or disclosure.

• 24*7 monitoring of network activity:
  Monitoring network activity for any unusual or suspicious behavior is an important aspect of cyber security. Security professionals should implement tools and processes to monitor network activity, including logs, traffic monitoring, and intrusion detection systems. This can help to identify and respond to potential security threats promptly.

• Have an incident response plan in place:
  Security professionals must have an incident response plan in place to handle security breaches. This plan should include clear procedures for how to respond to a security incident, who should be notified, and what steps should be taken to contain and mitigate the incident. A well-defined incident response plan can help to minimize the damage caused by a security breach and allow organizations to quickly return to normal operations.

• Regular vulnerability assessment:
  Performing vulnerability assessment on the security of systems and networks is an important aspect of cyber security. Vulnerability scans and penetration testing can help to identify and prioritize potential security vulnerabilities and can be used to help organizations better understand their cyber security posture. Security professionals should establish a regular schedule for vulnerability scans and penetration testing, and ensure that all systems and networks are included in the scope of the scan.

Top Cybersecurity Best Practices for Employees

It is often mentioned that humans are the weakest link in security. The majority of the cyber attacks were possible because the attackers were able to find an individual within the organization who can be manipulated. As cyber-attacks continue to become more frequent and sophisticated, it is essential for employees to be aware of the risks and to take proactive measures to protect themselves and their organizations from potential threats.

Here are some of the Top Cybersecurity practices that employees should keep in mind to help keep their systems and data secure.

• Using updated and patched systems and software:
  Outdated and vulnerable components are prone to attacks by hackers. Employees have access to a lot of sensitive data about the organization. Hence, employees need to make sure that they are using the latest and patched version of software and systems.

• Avoid clicking on suspicious links or attachments:
  One of the most common ways that attackers gain access to systems and networks is through phishing emails. These emails often include links or attachments that, when clicked, download malware or redirect the user to a malicious website. Employees should be wary of unsolicited emails, and should never click on links or attachments that they are not sure are safe.

• Be cautious when using public Wi-Fi:
  Public Wi-Fi networks can be a convenient way to access the internet, but they are also a major security risk. These networks are often unsecured, which means that anyone on the network can potentially access the data being transmitted. When using public Wi-Fi, employees should be sure to use a VPN to encrypt their data and protect it from prying eyes.

• Keep personal information private:
  Personally identifiable information(PII) is a valuable commodity for attackers, and employees should be careful to keep their personal information private. This includes information such as Social Security numbers, credit card numbers, and bank account information. Employees should be careful about sharing this information online and should be sure to use secure websites when entering personal information.

• Use encryption:
  Encryption is the process of converting data into a code that can only be read by someone with the correct decryption key. Encryption can help to protect sensitive data, both in transit and at rest. Employees should use encryption whenever possible, such as when sending sensitive information via email or storing sensitive data on their computers.

• Be aware of social engineering:
  Social engineering is the practice of manipulating people into performing actions or divulging sensitive information. Attackers often use social engineering tactics to trick people into revealing their passwords or other sensitive information. Employees should be aware of these tactics and be suspicious of any requests for sensitive information, especially from unknown sources.

• Use anti-virus and anti-malware software:
  Anti-virus and anti-malware software provide several benefits to help protect your computer and network from malicious software and hackers. This software is designed to detect and remove viruses from your computer. These programs scan your computer's files and memory for known viruses and can also scan incoming emails and downloaded files for potential threats.

• Keep backups:
  Creating regular backups of important data is an essential aspect of cyber security. In the event of a cyber-attack or other disaster, having a recent backup can make it possible to quickly restore systems and data to their pre-incident state. Employees should regularly create backups of their important files and store them in a secure location.

• Report suspicious activity:
  If an employee suspects that a cyber attack is underway, they should report it immediately to their IT department or security team. Employees should also be aware of the signs of a cyber attack and should be familiar with the organization's incident response plan.
