What are the best practices to secure your network from cyberattacks?

1. Make sure you system is patched up and all latest version is used. 2. Don't use legacy technology 3. Use Zero Trust framework to improve security on all layers.

1. Patch your systems once they are out. 2. Use password manager and MFA (Authenticator App Only)on all your accounts. 3. Think before you Click. 4. Role-based access control. 5. Encrypt data at rest, on transit 6. Enable Logging and monitoring and also perform access reviews.

Patch management addresses known vulnerabilities found in software. A critical prerequisite to effective patch management/vulnerability management that is often overlooked though is asset management. You can't patch what you don't know you have and high on the priority list for an attacker is finding those assets that have been overlooked.

Service consumers often have an unrealistic dependency on MSSPs to keep their subscribed security services and (by association) their operational processes up to date. Environments and operational processes are complex and often obfuscated. It is essential to adopt a shared-risk model and to not rely entirely upon the MSSPs (who often cannot or do not want the overhead of managing complex change) to keep you "secure".

Using secure network connections, ensuring communication between your browser and websites occurs via the encrypted HTTPS protocol. Avoiding the use of insecure Wi-Fi networks, particularly those from public places or unknown sources, to prevent interception or eavesdropping. Avoiding clicking on suspicious links or attachments, verifying their sources, checking for spelling errors or unusual characters, and relevance to the email's content to prevent phishing, spear-phishing, and whaling attacks. In addition to these best practices, consider using specialized network security platforms to safeguard your network from cyberattacks.

Passwords are good, but there are several ways to compromise or bypass them completely depending on the situation. They need to be paired with MFA and good zero trust practices.

While strong passwords are important, multi-factor authentication (MFA) elevates security significantly. Users should always adopt MFA when it’s technically feasible to do so. It’s also important to ensure that both factors of the MFA cannot be susceptible to a common source of compromise.

To use a strong passwords is good. However, you should have a schedule to change your password based on the importance and usual frequency. Remember that login's frequency is increasing your disclosure password's rate.

I would say: Use looong and unique passphrases with MFA, or go passwordless if you're equipped for it. Educate your users on the importance of using unique passwords, MFA, and password managers, but also how to stay safe on the Internet and not fall for phishing.

Strong passwords and MFA are necessary, but employees must be trained to protect company assets from phishing campaigns that can bypass multi-factor authentication. MFA fatigue is a real issue nowadays and must be dealt with through carrot-and-stick guidelines.

Encrypting data could take time for your data usage's activities. You can name your file in a format that only your internal organization know first. Let encrypt important data only. To be more careful, you should break them into many parts before encrypt. To join those parts, it should require a password

Crypto agility should also be a consideration in the design of encryption mechanisms on systems, taking into account the need to eventually migrate to Post Quantum Cryptography in the face of emerging threat posed by quantum computing.

While this section is focusing on end users, it is important to highlight that educate the them on data handling to know how to properly classify, store and share corporate data. Companies tend to spend millions on security tooling and not educating their employees on what tool to use to share data externally for example.

Proper configuration of firewalls and VPNs are essential to the success of defending against such threats. In addition, logging information should also be constantly reviewed to gain more information on potential intrusions, from which we can correlate with events/logs captured from other security monitoring devices (e.g. SIEM, HIDS).

firewalls and VPNs is too heavy and painful for none tech users. Let use some new technologies such as Zero Trust or SSS Tunneling for better approaching.

Sure this is totally right. Let build a cyber attack train program for you staff from junior level to manager level. You should categorize your information's risk to level training program and inter certification

Educate your staff on the most common mistakes that lead to a compromise. Define and mandate the protection of the assets and tools that are usually exploited or used to exploit users. Make staff aware of social engineering concepts and mandate the best security practices to ensure protection is followed. Regularly and continuously gauge the effectiveness of your education campaigns and mandate staff to test their security knowledge.

It's great having firewalls and NACs, but if nobody's monitoring what's going on, then it's a great waste of potential security. One thing a lot of companies overlook is a good old-fashioned NIDS (or the fancier version thereof, an NDR). Having a NIDS can expose more visibility of what's on your network. Finally, all of this observable data needs to be ingested into a SIEM and corroborated with some form of CTI. It's like I always say, "Take an engineering approach to building your security from the ground up, and you will be empowered to make top-down decisions correctly."

Strengthening Reputation: Demonstrating that a company conducts regular security tests can strengthen its reputation among customers and partners. It shows a commitment to security and the protection of customer data.

All organizations have technical debt and legacy equipment that is no longer supported by their manufacturers. Telecoms often have more legacy equipment than organizations in other industries, as their business models and investment cycles are measured in decades. While it's often infeasible to replace older equipment, telecoms can develop reference architectures that protect legacy devices in other ways, including jump servers, microsegmentation, intrusion prevention systems, privileged access management, and more. Other industries can learn from this approach as well, as every organization has some legacy equipment. With the potency of cyberattacks on the rise, doing nothing is not an option and falls short of the standard of due care.

To secure your network against cyberattacks, employ a multifaceted approach. Start with robust access controls, encryption, and regular updates for tech defense. Use intrusion detection and prevention systems for real-time threat identification. Educate employees on phishing and conduct audits for ongoing vigilance. A blend of technology, monitoring, and a well-informed workforce ensures comprehensive cybersecurity.

The best practices to protect your network against cyberattacks involve a multi-faceted approach. First and foremost, ensure that all software, operating systems, and security patches are regularly updated. Implement strong and unique passwords, and consider two-factor authentication for added security. Employ robust firewall and intrusion detection systems, and regularly monitor network traffic for anomalies.

Educate employees about cybersecurity best practices and the importance of identifying phishing attempts. Regularly back up critical data and have a solid incident response plan in place. Conduct security audits and vulnerability assessments to identify and rectify weaknesses. Lastly, stay informed about the latest cyber threats and adapt your security measures accordingly. A comprehensive and proactive strategy is crucial to safeguarding your network from cyber threats.

Good asset management is essential for securing your network. If you don't know which computers and operating systems being used it makes it that much more difficult to keep track of patch management. Also utilize a target approach to securing devices and accounts. Start with the bullseye and put the most mission critical systems and accounts in there. Access to items in the bullseye should be limited to the fewest amount of people with the most stringent of protections. From there work you're way out from ring to ring. Another important thing to remember is the 3-2-1 rule for data. 3 copies of your data (1 production and 2 backups). Those 2 backups should be stored on two different media types. And 1 of those backups should be offsite.
