Hardening Long Sleeve T-Shirts

This is a black background with white letters design to avoid Linux administrators to provide sudo privileges for every single permission denied they get, when trying to run any command with a non root user.

One of the most important activities in cybersecurity is to patch regularly the systems to fix the vulnerabilities that may affect it. Failing to do so will leave the system at risk and you'll need to pray the gods for not being attacked by a malicious actor.

Yet another security awareness design, this time related to one of the weakness to address in terms of Linux configuration or hardening. If you stop writing the previous commands in the history, you can avoid the passwords being wrote on it when admins use them in commands as parameters.

Administrators tends to su or login as root to perform privileged actions on Linux systems while they shouldn't. It is a bad practice to use root account so, instead, the recommendation is to use a non-root user to elevate with sudo to perform those actions or give them enough capabilities.

Instead of giving systematically sudo or suid privileges when a non root user cannot perform an action on the system, the Linux capabilities are one of the alternatives to keep the least privilege principle. This is a black background with white letters design version for the security awareness.

One of the ways to reduce the risk is to limit the impact in case of compromise so practicing least privilege is the way.

This is a cool and funny design to wear or to show what a Cybersecurity Professional prefers most of the times: deny by default. If there is no way to access then it is not possible to compromise. This is a black background design version with white letters.

Running out of file descriptors due to a DoS or DDoS attack on your website and it is crashing the whole system? Then ulimit is your friend. The ulimit command sets a limit of file descriptors to a user to avoid consuming all the resources in case of DoS attack.

A cool and funny way to remind one of the OWASP guidelines, the A5:2021 security misconfiguration. This design will guide your developers to follow the best practices and mitigate the risks of any default settings or credentials.

This should be mainstream when it comes to provide access or authorisation but, in some cases, it is not followed properly. Therefore, this design is to remind about this best practice.

An awareness design to avoid Linux administrators to give sudo privileges to the command less. This could lead unwanted privilege escalation.

A cool role design for a cyber security engineer with circuits details on the letters and a black background. Show it with proud and let everybody know that you are this kind of professional.

The United Kingdom flag design of the Cybersecurity Blue Team in badge style. Ideal for your peers working with you in the same cyber security group. Let's prove to the Red Team that they don't stand a chance to compromise anything!

Dark background version of a minimalistic design for threat hunters, a specialized cybersecurity profiles which analyzes and deploys new ways of detecting threats in the organization network.

Design about one of the ways that bad guys may use to compromise a target organisation network. If macros or scripts are allowed generally in office documents, then they could potentially use them to execute malware if one of the employees clicks or opens anything evil in a phishing email. A complete headache for cybersecurity team.

A good practice is to patch or update all the components and devices that belongs to the organisation network regularly. Failing to do so, will increase the risk of being compromised.

In cybersecurity, any security control needs to be two or more because if one of them fails, there's a second one, also known as compensatory control, to keep the organization assets safe. That's the fundaments of Defense in depth or layered defense.

The Sweden flag design of the Cybersecurity Blue Team in badge style. Ideal for your peers working with you in the same cyber security group. Let's prove to the Red Team that they don't stand a chance to compromise anything!

Instead of giving systematically sudo or suid privileges when a non root user cannot perform an action on the system, the Linux capabilities are one of the alternatives to keep the least privilege principle.

A design representing the well known TCP SYN attack that attackers may perform to produce DoS or DDoS on a victim system.

Great design to wear on mother's day with proud because your beloved mom is the best cybersecurity professional and well deserves this recognition. Don't miss the chance to do so. It is also appropriate for any other similar special day for her!

The Netherlands flag design of the Cybersecurity Blue Team in badge style. Ideal for your peers working with you in the same cyber security group. Let's prove to the Red Team that they don't stand a chance to compromise anything!

Stylish red version design for professionals working as Cybersecurity Engineers. Wear it with proud because your determination in this role is the key for success.

The less privileges you assign the more secure will be the system or the corporate network. That's the least privilege principle.

A great design for a mom who is proud of her son or daughter's profession and to give him or her the appropriate recognition.

Stylish design for professionals working as Cybersecurity Engineers. Wear it with proud because your determination in this role is the key for success.

Security controls are not perfect so you need to have multiple different controls and compensatory ones to reduce the risk of breach or compromise.

Put your trust in a cybersecurity specialised profiles, call the blue team that will defend your organization network in a gamification manner.

The principle of the Zero Trust architecture is to assume the breach inside your network, therefore, never trust any asset access before validation or authentication. Is like validating your cat before he can enter home.

Welcome to the CTF gamification arena where the blue team and the red team fight each other with one common objective: To proactively detect any vulnerability or weakness before the malicious actors or the bad guys. Use them with proud on such events to show what you are made of!! This is a design version with 4 Purple Team badge pack.

An awareness design to avoid Linux administrators to provide sudo privileges for every single permission denied they get, when trying to run any command with a non root user.

The less privileges you assign the more secure will be the system or the corporate network. That's the least privilege principle. This is a black background with white letters design version.
