You’re working from home and need to secure your network. What’s the best way to do it?

Absolutely, staying on top of software updates is a fundamental, yet often overlooked, aspect of cybersecurity. It's akin to keeping the locks on your doors robust and updated in the face of ever-evolving lock-picking techniques. These updates do much more than just introduce new features; they patch up vulnerabilities that could be exploited by cyber threats. The beauty of setting updates to automatic is that it ensures you're always protected without having to remember to check for and apply updates manually. It's a simple step, but its impact on network security and stability is immense. It's always surprising how such a straightforward practice can be a game-changer in safeguarding against potential cyber threats.

To secure your network while working from home, here are some best practices: 1. Update software: Regularly update the software on your devices to patch any security vulnerabilities. 2. Use a firewall: Use the firewall to monitor and control incoming and outgoing network traffic and also limit access to required ports and protocols. 3. Enable network segmentation: Separate your network from other parts of network by creating separate VLANs. 4. Use a VPN: Consider using VPN to encrypt your connection and protect your data when accessing sensitive information. 5. Secure your devices: Ensure that all your devices have up-to-date firmware, antivirus software and security patches installed to protect against malware and other threats.

The most important thing is if we have router with firewall function we can just make some set of rules to block unauthorized websites, and unauthorized downloads. Also, one thing in consideration is to make ensure we have strong login password or CLI to block or restricted access. This might make something 80% of network to be secured If we need 100% then we might have strong policies enforeced on firewall and other things.

?Securing your network is extremely important, and an essential step is effectively managing software updates. ? Consider it as strengthening your digital doors against changing cyber threats. ?Updates not only add new features but also fix vulnerabilities that are exploited by malicious individuals. ? Automating updates is crucial for continuous protection without the need for manual work. ?This straightforward practice greatly enhances network security, offering a strong defense against potential cyber threats. ?In the context of remote work, where home networks are the first line of defense, this approach becomes even more vital in fortifying the digital boundary against constantly evolving threats.

Invista em um software antivírus abrangente: Um pacote de antivírus abrangente é essencial para proteger você e seus funcionários contra uma variedade de amea?as, incluindo ataques de dia zero, malwares, spywares, vírus, trojans, worms e golpes de phishing. Essas suítes de seguran?a oferecem prote??o automática e atualiza??es contínuas para manter você seguro enquanto trabalha remotamente.

When working from home, you might access sensitive or confidential company data. Without proper security measures like a VPN with MFA, this information could be exposed to cyber threats. MFA ensures that even if a password is compromised, unauthorized users can't easily access the network and steal or corrupt data.

Using not only VPNs would be better also with some security features. Like having default loopback address or default login passwords for VPN login. Most of most important is to ensure our SSL and configuration certificates should be better one. Because malicious traffic over network might make strong network into malweb one.

VPN used to be secure solution but I believe everything needs to go more on zero trust side as VPN boxes have been exploited recently making them an insecure choice.

Utilize uma rede virtual particular (VPN): Conectar-se a redes Wi-Fi n?o seguras pode ser arriscado. Uma VPN estabelece uma conex?o segura para trabalhar em arquivos e visualizar fotos pessoais salvas na nuvem.

1. Enhanced Security: A VPN encrypts your internet traffic, protecting it from potential eavesdropping and cyber threats, especially when using public Wi-Fi networks. 2. Privacy Protection: Using a VPN shields your browsing activities from ISP monitoring and prevents websites from tracking your real IP address, thereby preserving anonymity online. 3. Bypassing Geo-restrictions: With a VPN, you can access region-locked content or services by connecting to servers in different countries, expanding your digital accessibility. 4. Secure Remote Access: VPNs enable secure access to company resources and internal networks while working remotely, ensuring data confidentiality and integrity. 5. Risk Mitigation

One crucial step in securing your home network is regularly updating and strengthening your passwords. Ensure that your passwords are unique, complex, and include a combination of letters, numbers, and special characters. Implement a password manager to generate and store strong, encrypted passwords for your various online accounts. Additionally, enable multi-factor authentication (MFA) whenever possible, adding an extra layer of security to prevent unauthorized access to your accounts. Regularly changing passwords and using secure authentication methods significantly bolster the security of your home network.

Mantenha os membros da família longe dos dispositivos de trabalho: Lembre-se de que, durante esses tempos, os computadores da empresa est?o mais expostos a crian?as pequenas e outros membros da família. Certifique-se de proteger seus dispositivos com senhas e evite que familiares acessem seus notebooks, celulares e outros tipos de hardware. Mantenha suas senhas sempre seguras.

1. Regularly Change: Set a routine to change your passwords at least every few months, minimizing the impact of potential data breaches and unauthorized accesses. 2. Strong and Unique: Create complex passwords using a mix of upper and lower case letters, numbers, and symbols for each account to enhance security. 3. Password Manager: Utilize a reputable password manager to generate and store unique passwords for different accounts, reducing the risk of using easily crackable or repetitive passwords. 4. Multi-Factor Authentication (MFA): Enable MFA wherever possible to add an extra layer of security by requiring additional verification steps beyond just entering a password. 5. Monitoring Breach Databases

This has very little to do with your home network. It only relates to any local passwords on devices you use inside your home. MFA is unlikely to be an option for these for most, it’s therefore even more important for the passwords to be complex & unique. If you access your devices with a browser and the browser’s pwd manager is secure, use that to store them. Even if you don’t use a browser to access some devices, you can still use the same browser to store the passwords; at least they’ll all be in one place. For all other passwords, same applies but pay additional scrutiny to any related to finances and sensitive information. Do not use a service without it supporting MFA/2FA and preferably an associated app rather than text messages.

?Change default credentials with strong, unique ones. ?Enable WPA3 encryption for Wi-Fi security. ?Regularly update router firmware for security patches. ?Set a strong Wi-Fi password, avoiding easily guessable ones. ?Modify default SSID and avoid personal information. ?Disable remote management to prevent unauthorized access. ?Use a VPN for additional network encryption. Implement MAC address filtering for approved devices. ?Turn off Wi-Fi Protected Setup (WPS) for added security. ?Regularly monitor connected devices for any anomalies. ?Create a separate guest network with unique credentials. ?Ensure physical security of the router to prevent tampering.

Some great advice here so I’ll try not to be too repetitive. - all very well changing the SSID name, but why not hide it as well. What you can’t see… - update firmware regularly and use ultra secure passwords - turn off ANY unnecessary services that could be exploited - do not allow ANY external access to your router(s) - maintain a separate GUEST network SSID and preferably on a separate router/physical network if possible. Only allow this network outbound access, not access to your internal private network - enable logging on the router if it’s capable - keep yourself educated about the latest threats and network security recommendations

Proteja seu roteador e a sua rede Wi-Fi doméstica: Altere o nome da sua rede (SSID) e configure senhas fortes para impedir que terceiros acessem seus arquivos confidenciais.

1. Change Default Credentials: Modify the default router login credentials to a strong and unique combination to prevent unauthorized access. 2. Firmware Updates: Regularly update the router's firmware to patch security vulnerabilities and ensure it has the latest security features. 3. Strong Encryption: Utilize WPA3 or WPA2 encryption standards for Wi-Fi networks, and avoid using outdated or weak encryption protocols. 4. Network Segmentation: Implement network segmentation to separate devices into different subnetworks, enhancing security by controlling access between devices. 5. Disable Remote Management 6. Guest Network 7. Firewall Configuration

Installing a firewall is essential to control incoming and outgoing network traffic and protect your home devices from potential threats. Many home routers come with built-in firewalls that can be configured to filter traffic based on predefined security rules. Ensure that your firewall is enabled and properly configured to block unnecessary ports and services. Additionally, consider using personal firewall software on your individual devices for an added layer of protection. A firewall acts as a barrier between your home network and the external world, helping prevent unauthorized access and enhancing the overall security of your home environment.

1. Network Firewall: Establish a network firewall to regulate incoming and outgoing traffic, inspecting data packets and ensuring only authorized communications pass through. 2. Host-Based Firewall: Install host-based firewalls on individual devices to monitor and control network traffic at the device level, adding an extra layer of security. 3. Application Layer Security: Utilize application layer firewalls to scrutinize and filter traffic based on specific applications or protocols, bolstering protection against targeted attacks. 4. Unified Threat Management (UTM) 5. Regular Updates 6. Rule Configuration 7. Intrusion Prevention Systems (IPS)

This goes hand in hand with number 4 Securing Your Router really as any router these days worth its salt will include some level of firewall capability. It’s just a packet filter after all. If yours does not or if it’s a service provider router that you cannot configure this on, replace it with one that will. As I’ve said in 4, limit inbound traffic. No remote access. In fact, you can quite easily block all inbound traffic for extra security. If the firewall is capable, it can also limit access to outbound sites. Those you don’t want your kids visiting for instance and any that contain malware. Some services will support auto updates of this type of security policy but some inbound access will need to be granted to enable it.

User awareness should be top priority, no matter how many technology you use will all be useless if the network undergoes cyber attack Have trainings for new joiners and periodically have refresher training. Send emails to get generate awareness among employees

Invest time in educating yourself about cybersecurity best practices to fortify your home network. Stay informed about the latest threats, vulnerabilities, and security updates relevant to your devices and software. Understand the importance of keeping your operating system, antivirus, and other software up-to-date to patch known vulnerabilities. Be cautious of phishing attempts and practice safe browsing habits. Familiarize yourself with the security features of your home router, such as Wi-Fi encryption protocols and guest network options. By staying informed and adopting proactive cybersecurity habits, you empower yourself to create a more resilient and secure home network.

Separate your work activity from home activity. Do not expose your work setup to the less relaxed (and less secure) home activity.

If possible keep the work activity on a different network then office network. Like you can have a 4g/5g dongle for work and normal wifi for home. And if you can’t, then make sure your router firmware is upto date and you have a strong password set for that and a different username then admin. change the password every 6 month iff possible. Follow the WFH policy of your organisation and make sure when you leave your desk at home, your work machine is locked.

First, take a look at your IoT devices – items like your smart refrigerator, oven, garage door opener, and cameras. These gadgets essentially function as compact computers. However, unlike your laptop or smartphone, you probably don't have much control over them, nor a clear insight into their security protocols. To safeguard your network, it's advisable to segment these devices. This involves placing them on a separate subnet that's isolated from the more sensitive parts of your network. Doing so minimizes your risk, ensuring that even if their security isn't robust, your crucial data remains uncompromised.

1) Use your work asset for work only. The company can see everything you do. If you're in the habit of mixing work and personal, break it. If you don't own a personal computer or laptop, buy one and set it next to your work system. 2) If you're not network savvy or you don't own network hardware that allows you to create a dedicated segmented network, fire up your home WiFi router's Guest network and connect your work laptop to it.

Use enclave architecture that combines zero trust with secure connectivity such as VPN or NetScaler (aka Citrix). Make sure you security controls and measures aligned with your asset/data classification to understand what needs to be protected the most, and adjust your architecture accordingly.
