Purdue network architecture. Network Architecture and Design. Network Architecture and Design.
Firewalls, intrusion detection systems, regular patching, and endpoint protection act as the digital equivalent of preventive pest spray. CISO takeaway: Cyber threats evolve constantly, with attackers using sophisticated tactics like ransomware-as-a-service or AI-driven malware.
Although cybercrime as a whole has seen a rise during the pandemic, arguably ransomware has been one of the more successful and lucrative attack types. Our own research report, the State of Encrypted Attacks Report 2020 , found that there had been a 500 per cent rise in ransomware compared to 2019. Security hygiene is the best defence.
The directive applies to any networking devices — such as firewalls, routers and load balancers — that allow remote authentication or administration. On February 2, KrebsOnSecurity broke the news that attackers were exploiting a zero-day vulnerability in the GoAnywhere FTP appliance by Fortra.
This requires sys admins to reconfigure the uncomplicated firewall (UFW) configuration file on the server and insert new rules for Docker. Kelly said companies are moving at a frantic pace to move to containerized architectures to help with scalability and redundancy – and they often don’t consider the security implications. .
In addition to standard firewalls , features in UTMs often include intrusion detection and prevention systems (IDPS) , secure web gateways , secure email gateways , remote access , routing and WAN connectivity. Some vendors have ditched the UTM label and prefer to call their tools next-generation firewalls (NGFW). URL filtering.
We’ll get into specifics below, but here are five steps to prevent ransomware attacks, along with links to jump ahead: Harden against attacks : Patch, update, and change settings to harden resources against attacks. Hardening includes, but is not limited to: Block unused ports on servers and firewalls. Anti-DDoS Architecture.

However, the rise of the modern distributed/hybrid work model increases the attack surface for users and endpoints due to phishing, ransomware, and myriad other threats to the now "extended" corporate network. Zero Trust leverages multiple People, Process & Technology safeguards (layered architecture).
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?
Security leaders have fought to keep pace with rapidly evolving ransomware tactics for decades, and 2024 served as yet another reminder of the dynamic and persistent nature of the ransomware threat. The latest ThreatLabz Ransomware Report offers deep analysis of 4.4 million ransomware attacks blocked by the Zscaler cloud (a 17.8%
The tools also depend upon physical controls that should also be implemented against malicious physical access to destroy or compromise networking equipment such as routers, cables, switches, firewalls, and other networking appliances. These physical controls do not rely upon IT technology and will be assumed to be in place.
The problem with following the fast-and-risky mantra is that many failures turn out to be architectural in nature, are not easy to fix and can all too easily escape notice or, worse, be ignored. Legacy defenses at the gateway, firewall, endpoint and application levels must be rearchitected and scaled-up. Embracing complexity.
The group is also the author of the NotPetya ransomware that hit hundreds of companies worldwide in June 2017, causing billions worth of damage. According to WatchGuard , Cyclops Blink may have affected roughly 1% of all active WatchGuard firewall appliances. ” Cyclops Blink is sophisticated malware with a modular structure.
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.
Fortunately, vendor surveys identify five key cybersecurity threats to watch for in 2024: compromised credentials, attacks on infrastructure, organized and advanced adversaries, ransomware, and uncontrolled devices. Infrastructure Protection Defense against DDoS and DNS attacks starts with effective network security architecture.
And yet it remains all too easy for malicious hackers to get deep access, steal data, spread ransomware, disrupt infrastructure and attain long run unauthorized access. Companies are obsessed with leveraging cloud-hosted IT infrastructure and the speedy software development and deployment that goes along with that. Is that fair?
When the internet arrived, the network added a firewall to protect networks and users as they connected to the world wide web. Technical controls may be implemented by: Hardware appliances : switches, routers, firewalls, etc. In a complex, modern network, this assumption falls apart.
The hacker was able to infiltrate the water treatment plant because its computers were running on an outdated operating system, shared the same password for remote access and were connected to the internet without a firewall. For example, ransomware could permanently encrypt Internet of Things (IoT) traffic lights, making them unusable.
The firewall emerged as the cornerstone around which companies were encouraged to pursue a so-called defense-in-depth strategy. Intrusion detection, intrusion prevention and sandboxing technologies got bolted onto the firewall. A paradigm shift in fundamental network architecture is sorely needed. SASE fundamentals.
Whether caused by market conditions, legacy technology, or external threats such as ransomware, built-in resilience to meet these challenges has risen to the top as a digital transformation key performance indicator (KPI). . Replatform complex, multigenerational systems to modern architectures, such as private and public cloud. .
Firewalls may allow these packets through and cause server CPUs to become overwhelmed due to resources wasted analyzing and discarding these packets. However, some criminals also use the DDoS attack to distract victims and cover up evidence of data theft, ransomware, and other attacks. Harden infrastructure. DDoS playbook.
Organizations have respondedand must continue toby adopting AI-powered cybersecurity tools and implementing zero trust architecture as a critical countermeasure. Ransomware-as-a-service played its part in another rush of ransomware in 2024, contributing to a 57.8% increase in extorted companies listed on data leak sites.
Ransomware and stolen customer data can put an enterprise out of business for months. Network design and architecture. Architecting a robust network with multiple layers of firewall protection, redundant pathways for both external and internal and isolating critical data is paramount in limiting the damage done by a threat actor.
It’s often the first step to perform further actions such as data thefts, defacing, or even ransomware attacks that have caused severe damages to many organizations in recent years. This attack relies on a client-server architecture and consists of using other protocols such as TCP or SSH to tunnel malware through DNS requests.
The phishing strategy is another reason for adopting a zero-trust architecture , which means assuming that an email from outside the organization is malicious until proven otherwise, according to Stefano De Blasi, cyber threat intelligence analyst with digital risk protection company Digital Shadows.
According to WatchGuard , Cyclops Blink may have affected roughly 1% of all active WatchGuard firewall appliances. The group is also the author of the NotPetya ransomware that hit hundreds of companies worldwide in June 2017, causing billions worth of damage. ” reads the advisory published by TrendMicro.
