Public Key Infrastructure (PKI) connects cryptographic public keys to asserted identities and applications through certificates, issuers, trust anchors and validation rules. A self-signed certificate is a certificate whose signature verifies using its own public key; a private key is not “self-signed.” This distinction matters when configuring an internal service: a signature may show that a […]
Penetration testing tools in 2025 exist in a cybersecurity environment that is fundamentally different from earlier eras. Modern digital ecosystems are no longer static collections of servers and endpoints but highly distributed, continuously changing infrastructures spanning cloud platforms, hybrid networks, edge devices, and containerized workloads. This shift has forced ethical hacking tools to evolve from […]
For decades, traditional firewalls served as the primary line of defense for organizational networks, operating on the relatively simple principle of allowing or blocking traffic based on IP addresses and port numbers. This approach worked reasonably well in an era when network traffic was largely predictable and applications used fixed, well-known ports for communication. However, […]
The cybersecurity environment that organizations navigate in 2025 bears little resemblance to the threat landscape of even a decade ago. What was once a domain primarily concerned with preventing opportunistic attacks from individual hackers has evolved into a sophisticated battlefield where nation-state actors, organized criminal enterprises, and well-funded adversarial groups deploy advanced persistent threats against […]
The CompTIA CySA+ certification has long been recognized as one of the most practical and career-relevant credentials in the cybersecurity field. When CompTIA retired the CS0-002 exam and introduced CS0-003, it was not simply a routine version update. The shift represented a meaningful evolution in how the industry thinks about threat detection, incident response, and […]
In today’s dynamic cybersecurity environment, the role of digital forensics and incident response (DFIR) has become increasingly critical. Organizations large and small are under constant threat from cyberattacks, data breaches, and internal policy violations. When incidents happen, teams must act fast, not only to contain damage but to investigate what occurred, how it happened, and […]
The Certified Ethical Hacker credential, universally recognized within the information security community by its abbreviation CEH, is a professional certification developed and administered by the EC-Council, which stands for the International Council of Electronic Commerce Consultants. Established in 2003 in response to growing demand for formalized training and credentialing in offensive security techniques, the CEH […]
The world of enterprise networking has long been dominated by a handful of powerful names, but few rivalries have sparked as much debate in recent years as the one between Ubiquiti and Cisco. On one side stands Cisco, a decades-old titan whose name has become almost synonymous with enterprise-grade networking infrastructure. On the other side […]
Legacy exam context: The former CCNA Routing and Switching credential and the old two-exam pathway were retired when Cisco consolidated its associate networking certifications. The active CCNA pathway uses the 200-301 exam; the routing, switching, addressing and troubleshooting skills remain central, but a candidate must not schedule a retired CCNA R&S examination. The Cisco Certified […]
The Cisco Certified Network Professional certification stands as one of the most respected and widely recognized credentials in the global networking industry, validating the advanced technical knowledge and practical skills that professional-level network engineers need to design, implement, and troubleshoot complex enterprise network infrastructures. Earning the CCNP places a networking professional firmly in the category […]
The old CCNA CyberOps naming has been superseded by CCNA Cybersecurity. Cisco’s current associate exam is 200-201 CCNACBR, covering security concepts, monitoring, host-based analysis, network intrusion analysis, and policy and procedures. CCNP Security is a professional track with its own current core and concentration exams; do not use retired CBROPS labels or prerequisites as present-day […]
Cisco regularly retires or renames examinations as technology and its certification structure change. The headline of this legacy article refers to ‘nine’ retirements, but a candidate in October 2026 should not interpret that old headline as a newly announced list of nine exams. Cisco’s official retired-exams database gives a date and applicable successor for each […]
Cisco DevNet helped normalize a change in network engineering: infrastructure became something professionals increasingly managed through software, APIs, version control, and repeatable automation rather than commands typed on individual devices. Its original certification names made sense when networking and application development were commonly treated as separate disciplines. The skills it helped popularize are still valuable, […]
Cisco’s original CCNA Cyber Ops certification was retired during the company’s 2020 certification restructuring. Its successor was called CyberOps Associate for a period, and the active associate-level security operations credential is now named Cisco Cybersecurity Associate, using the 200-201 CBROPS exam family. These names belong to related stages of the program, not three simultaneously available […]
YANG emerged in 2010 as a specialised data modelling language, originally defined to describe data sent over the NETCONF network management protocol. It provides a standardised framework for defining how network devices are configured and managed, enabling the detailed specification of network devices’ configuration, operational data, and policies in a structured, modular, and extensible manner.
