CCNA CyberOps Chapter 1 Exam Online

The Stuxnet malware program is an excellent example of a sophisticated cyberwarfare weapon. In 2010, it was used to attack programmable logic controllers that operated uranium enrichment centrifuges in Iran.

Many free and open wireless hotspots operate with no authentication or weak authentication mechanisms. Attackers could easily capture the network traffic in and out of such a hotspot and steal user information. In addition, attackers might set up a “rogue” wireless hotspot to attract unsuspecting users to it and then collect information from those users.

Security operations centers (SOCs) can provide a broad range of services to defend against threats to information systems of an organization. These services include monitoring threats to network security and managing comprehensive solutions to fight against threats. Ensuring secure routing exchanges and providing secure Internet connections are tasks typically performed by a network operations center (NOC). Responding to facility break-ins is typically the function and responsibility of the local police department.

Cyberwarfare is Internet-based conflict that involves the penetration of the networks and computer systems of other nations. Organized hackers are typically involved in such an attack.

In a SOC, Tier 3 SMEs have expert-level skills in network, endpoint, threat intelligence, and malware reverse engineering (RE). They are deeply involved in hunting for potential security threats and implementing threat detection tools.

In a SOC, a ticketing system is typically used for a work flow management system.

IoT devices commonly operate using their original firmware and do not receive updates as frequently as laptops, desktops, and mobile platforms.

In a SOC, the job of a Tier 1 Alert Analyst includes monitoring incoming alerts and verifying that a true security incident has occurred.

Technologies in a SOC should include the following:
Event collection, correlation, and analysis
Security monitoring
Security control
Log management
Vulnerability assessment
Vulnerability tracking
Threat intelligence
Proxy server, VPN, and IPS are security devices deployed in the network infrastructure.

Within a year, there are 365 days x 24 hours a day x 60 minutes per hour = 525,600 minutes. With the goal of uptime 99.999% of time, the downtime needs to be controlled under 525,600 x (1-0.99999) = 5.256 minutes a year.

Each type of cybercriminal has a distinct motivation for his or her actions.

A security information and event management system (SIEM) combines data from multiple sources to help SOC personnel collect and filter data, detect and classify threats, analyze and investigate threats, and manage resources to implement preventive measures.

Script kiddies is a term used to describe inexperienced hackers.

The CompTIA Cybersecurity Analyst (CySA+) certification is a vendor-neutral security professional certification.

A cybersecurity specialist needs to be familiar with the characteristics of the different types of malware and attacks that threaten an organization.
