The exam will cover the following topics:TCP/IP (Protocols And Networking Basics)Network Discovery ProtocolsNetwork Architectures, Mapping And Target IdentificationNetwork Scanning & FingerprintingTesting Network ServicesCryptographyActive Directory Security BasicsLinux And Windows Security BasicsCommon Vulnerabilities Affecting Windows ServicesTesting Web Servers And FrameworksBasic Malware AnalysisSocial Engineering AttacksNetwork Security Tools And Frameworks (Such As Nmap, Wireshark etc.)Open-Source Intelligence Gathering (OSINT)Database Security BasicsTLS Security BasicsPassword StorageWhat Is The Experience Needed To Take The Exam?This is an entry-level exam. It checks the understanding of core fundamentals in relation to network security topics. Candidates should have knowledge of common security misconfigurations, the best security practices, defense-in-depth measures as well as an overview of how vulnerabilities can be exploited in the real world scenario.What Is The Format Of The Exam?The exam includes Multiple Choice Questions (MCQs) covering the syllabus. The time duration of the exam is 60 minutes. The exam will be proctored but can be taken online, anytime (on-demand) and from anywhere. The exam will cover a variety of questions which are both factual and scenario based.Sample Question:Q. How many usable TCP/UDP ports are there?A. 65536B. 65535C. 63535D. 65335Correct Answer: B. 65535Explanation:The total number of usable TCP/UDP ports each is 65,535. This count includes ports ranging from 0 to 65,535. The port field is of 16 bit in the header. So, there will be 2^16= 66536 ports. It will range from 0 to 66535. Note: Port 0 is reserved and not considered part of the usable port range for regular network communication. So, total number of usable ports are 65535. ***Gift: Decode this base64 string "Q05TUF83MF9PRkY=" in order to get the discounted code. ***
