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 […]
Ubiquiti can compete for some enterprise networking projects, but the term “enterprise” does not describe one uniform requirement. A single-building office with a small operations team, a school district with many sites and a bank with strict recovery targets may all need switching, wireless and firewalling; their support, compliance, identity and operational demands differ sharply. […]
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 former CCNA […]
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 role of a DevOps engineer has evolved significantly over the past decade, shifting from a position that primarily required operational knowledge of servers and infrastructure to one that demands a genuine and sophisticated level of programming competency. Organizations that once hired DevOps professionals primarily for their ability to manage configurations, monitor systems, and respond […]
The old CCNA CyberOps naming has been superseded by CCNA Cybersecurity.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 […]
Network Operations Center professionals occupy a uniquely positioned role within the technology industry, sitting at the intersection of infrastructure monitoring, incident response, systems analysis, and operational continuity. The NOC environment is defined by constant data streams, alert fatigue, time-sensitive escalations, and the need to make quick, accurate decisions based on incomplete information under pressure. These […]
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 in 2020. Its successor used the CyberOps Associate name for a period; Cisco now lists the active security-operations credential as CCNA Cybersecurity, with the 200-201 CCNACBR exam. Earlier materials may refer to the same exam family as CBROPS. These are successive names, not separate active associate-level tracks. […]
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. […]
The Certified Ethical Hacker certification, issued by EC-Council, has established itself as one of the most recognized credentials in the cybersecurity field since its introduction in the early 2000s. It validates that a professional understands how to think and operate like a malicious attacker in order to identify and address security weaknesses before they can […]
Credential attacks do not all work the same way. One actor may guess passwords through a live login screen, another may try one common password across hundreds of accounts, and another may replay usernames and passwords exposed at an unrelated service. An attacker who has obtained password hashes can test guesses offline without sending any […]
The cybersecurity certification landscape offers professionals dozens of credentials to pursue, but few carry the weight and recognition of the two flagship designations offered by ISACA: the Certified Information Systems Auditor and the Certified Information Security Manager. Both certifications are globally respected, both require demonstrated professional experience, and both represent serious investments of time, money, […]
DHCP, which stands for Dynamic Host Configuration Protocol, is one of the foundational technologies that keeps modern networks running without constant manual effort. Every time a device joins a network, it needs an IP address, a subnet mask, a default gateway, and DNS server information before it can communicate with other devices or access the […]
