Role Based Firewalls - New products on the anvil

Devices that have varied capabilities are increasing in number. This would lead to the inevitable deluge of devices connecting through Bluetooth, Wifi, Wimax, Fiber and any other medium that is considered good enough for data to be carried over.

The present set of tools that we use for securing networks are part of the risk management stance of an organization. The complexity of the varied devices is making it much more difficult and the balance between productivity and the technology advantage is lost if the organization does not use the latest in technologies.

We are seeing Contractors and end users who want to use their own devices. They want to connect to "The Networks" and the Infosec practitioner is to provide the needed connectivity to resources at the same time ensuring that the data is protected. The Contractor may work for our competitor, how do we ensure that he has access to systems that he needs access to. This is where the new breed of products would come in. The Role Based Firewalls. These rules are to applied based on the role assigned to the user, may be this system needs to talk to the project management and ERP systems to ensure that the Contractor gets to connect to the right set of services.

Lets check out a example scenario. A contractor connects to the system and he has been assigned into the Contractor group in the Active Directory. This same Contractor is also assigned into few projects where his expertise is required. A set of resources are assigned as being required for the Contractor to deliver his services. Based on this profile, the Application Proxy firewall creates a virtual firewall based on the Contractor settings and assigns him to channel all his traffic through that filter.

Is there a product that does something like this? If not I take credit for conceptualizing such a system.

Where are we headed ... A crystal ball into Cybersecurity in the next five years .. Are we ready?

  The future of Cyber Security: Trends and Predictions for the Next 5 years The field of cybersecurity is constantly evolving, and the threats are only getting more sophisticated. In the next five years, we can expect to see a number of trends emerge in the field of cybersecurity, including: The rise of artificial intelligence (AI). AI is already being used by cybercriminals to develop more sophisticated and targeted attacks. As AI continues to develop, it is likely that cybercriminals will be able to use it to even greater effect. The increasing use of cloud computing. Cloud computing has many benefits, but it also introduces new security challenges. Cloud-based data is often more vulnerable to attack than data that is stored on-premises. The growth of the Internet of Things (IoT). The IoT is connecting billions of devices to the internet, which creates a vast new attack surface for cybercriminals. IoT devices are often poorly secured, making them easy targets for attack. The shor...

The Shifting Landscape of Knowledge and the Nobel Prize

Our recent conversation sparked some interesting thoughts about the prestigious Nobel Prize and the distribution of its recipients across the globe. Inspired by a user's search history, we delved into the fascinating patterns and potential implications of who gets recognized for groundbreaking achievements. The initial point of discussion centered on the user's search activity, which revealed an interest in various scientific and technological topics, as well as a specific search for "Nobel Prize winners by country." This led us to explore the geographical distribution of Nobel laureates, and a question arose: why does it seem that certain schools and countries, particularly in the West, have a higher representation? We considered several factors that might contribute to this observation: Historical Dominance in Science: Historically, Western nations have often been at the forefront of scientific research due to earlier investments and established infrastructure. V...

Red Team Blue Team Exercises - A Roadmap to follow to test the efficacy of controls

  Scenario 1: Phishing Attack Red Team Playbook Day 1: Send out phishing emails to the blue team. Monitor the blue team's response. Day 2: Analyze the blue team's response and identify any vulnerabilities. Report the findings to the blue team. Blue Team Playbook Day 1: Train employees on how to identify and avoid phishing emails. Monitor for phishing emails. Day 2: Analyze the phishing emails sent by the red team. Identify any vulnerabilities in the organization's phishing detection and response processes. Develop a plan to improve the organization's phishing detection and response processes. Analysis The red team's phishing attack was successful in getting several employees to click on the phishing links. This shows that the organization needs to improve its employee training on phishing awareness. The blue team was able to identify and contain the phishing attack, but it took them several hours to do so. This shows that the organization needs to improve its phishi...
