According to WatchGuard , Cyclops Blink may have affected approximately 1% of active firewall appliances, which are devices mainly used by business customers. Cyclops Blink has been found in WatchGuard’s firewall devices since at least June 2019. As we learned from NotPetya, these attacks can spread around the world.
Setting up a firewall is the first step in securing your network. A successful firewall setup and deployment requires careful design, implementation, and maintenance to effectively improve your network integrity and data security. Verify that the chosen firewall can meet your security standards and functions.
As organizations work to establish AI governance frameworks, many are taking a cautious approach, restricting access to certain AI applications as they refine policies around data protection.U.S. Traditional security models rooted in firewalls and VPNs cannot keep up with the speed and sophistication of AI-powered threats.
government agency in charge of improving the nation’s cybersecurity posture is ordering all federal agencies to take new measures to restrict access to Internet-exposed networking equipment. The directive comes amid a surge in attacks targeting previously unknown vulnerabilities in widely used security and networking appliances.
This requires data-level protections, a robust identity architecture, and strategic micro-segmentation to create granular trust zones around an Organization’s digital resources. Think of it like the government or military’s “need-to-know” policy. The Zero Trust journey. The answer is simple.
What further compounds an already complex architectural and security landscape is the fact that critical infrastructure industries in various countries tend to be either partially or fully government controlled; with many providing “essential services” such as Healthcare, Water, Power, Emergency Services and Food production.
Cisco Secure Firewall integrations. Cisco Secure Firewall has several new partner integrations. CyberArk reduces VPN risk with MFA enforcement on any VPN client that supports RADIUS; including Cisco Secure Firewall. HashiCorp (Terraform) provides infrastructure automation and now supports Secure Firewall ASA.
Implement Multi-Layered Security A multi-layered approach, combining firewalls, intrusion detection systems (IDS), and endpoint security, can help detect and mitigate threats before they escalate. The Role of Regulators and GovernmentsGovernments and regulatory bodies play a critical role in combating cyber threats like FASTCash.
Traditional perimeter-based security models are no longer sufficient to protect against sophisticated attacks that can easily bypass firewalls and other boundary defenses. The key steps for successful deployment Implementing a Zero Trust architecture is a strategic and multi-faceted process that requires careful planning and execution.
This new integration supports Umbrella proxy, cloud firewall, IP, and DNS logs. This integration expands on Elastic’s on-going expansion of Cisco integrations including ASA, Nexus, Meraki, Duo and Secure Firewall Threat Defense. New Cisco Firepower Next-Gen Firewall Integrations. Read more here. Read more here.
On one hand, threat actors have already begun exploiting fresh attack vectors, borne of this rising complexity, and, on the other, government authorities and industry standards bodies are insisting on compliance with increasingly cumbersome data-handling security rules.
Symantec this week reported a highly sophisticated malware called “Backdoor.Daxin” that “appears to be used in a long-running espionage campaign against select governments and other critical infrastructure targets” and appears to be linked to China. The malware then sends information back to remote servers.
A PDNS service uses existing DNS protocols and architecture to analyze DNS queries and mitigate threats. The National Security Agency (NSA) and Cybersecurity and Infrastructure Agency (CISA) released a joint information sheet Thursday that offers guidance on the benefits of using a Protective Domain Name System (PDNS).
Firewalls and web application firewalls ( WAFs ) filter network traffic. Firewalls and Web Application Firewalls (WAF): Firewalls regulate network traffic and defend against external threats, whereas WAFs protect web applications by monitoring and filtering HTTP/HTTPS requests from potential threats.
The conference’s focus on cyber resilience doesn’t mean that organizations should abandon core security defenses like EDR , access control and firewalls , but they should be prepared for the advanced threats that will, at some point, get past them. Also read : Is the Answer to Vulnerabilities Patch Management as a Service?
In 2020, the SolarWinds supply chain attack opened backdoors into thousands of organizations (including government agencies) that used its services, while late last year, the far-reaching Log4J exploit exploded onto the scene. New major exploits are being revealed with almost clockwork regularity. So where do we go from here?
Network layer: Protects data in transit and ensures safe network paths by utilizing firewalls, VPNs , and secure routing protocols. Application layer: Includes app-level security features such as API, web application firewalls (WAFs) , and endpoint protection to protect user interactions and app data.
Applying data and digital governance across the organization for a rapid response to disruptions. Replatform complex, multigenerational systems to modern architectures, such as private and public cloud. . It encompasses agility and speed. Building in security through automated data privacy compliance and zero trust access .
Firewalls may allow these packets through and cause server CPUs to become overwhelmed due to resources wasted analyzing and discarding these packets. Government officials offer periodic warnings for IT teams to be on alert against DDoS attacks, but they rarely cite the potential motivation. In 2020 the U.S. Harden infrastructure.
“They leveraged a compromised end-user account from Constant Contact, a legitimate email marketing software company, to send phishing emails to more than 7,000 accounts across approximately 350 government organizations, IGOs and NGOs,” Das told eSecurity Planet.
Several factors contribute to API sprawl including: Adoption of cloud-native design patterns and microservices architectures. REST still dominates much of the API landscape but GraphQL is also gaining adoption, as is gRPC within microservice architectures. Use of API-enabled cloud infrastructure. How did we get here?
Security services and tools include anti-DDoS , SOCaaS , web application firewalls (WAF), data encryption , and more. Also Read: Top Web Application Firewall (WAF) Vendors.

Now we’re just CERT, we’ve grown beyond computer emergency response and within SEI, we do have three big things for not only DoD, our principal sponsor but across government and industry. One, we work to modernize software development and acquisition, because code is fueling society. I’m absolutely thrilled. I think it’s a strength.
To be successful, an attacker must gain access to the 5G Service Based Architecture. Network Functions Virtualization (NFV) is a virtualized network infrastructure where typical network functions – like firewalls , routing, and SD-WAN – can be installed as software through abstraction. 5G Systems Architecture.

Additionally, as fundamental parts of this complete architecture, adherence to safe API design standards and compliance with data protection laws reinforce APIs against a variety of cyber risks. A secure API architecture serves as a strong foundation for all that, designed with security in mind.
In most cases, attacks targeting APIs go undetected as they are generally considered as trusted paths and lack the same level of governance and security controls. There are numerous past examples in which vulnerabilities concerning remote access software, webservers, network edge equipment and firewalls have been used as an entry point.
Hackers targeted a wide range of organizations, such as banks, mail services, Bitcoin sites, VoIP providers, vaccination registration portals, information security media, gaming platforms, government sites, and even security agencies.
