دانلود کتاب +CompTIA Security – برای اصول امنیت شبکه، ویرایش هشتم

Astronomical, enormous, humongous—these are all words to describe the impact and scope of cyberattacks today. A security operations center at a port authority reports that they receive 40 million attempted cyberattacks each month. The total number of instances of malware has grown from 182 million in 2013 to over 1.34 billion today. Cybercrime has been called the “greatest transfer of economic wealth in history,” and it is estimated that it could reach $10.5 trillion annually by 2025. And the recent introduction of artificial intelligence (AI) tools has only heightened cybersecurity attacks. A 135 percent increase in phishing and spam emails has been directly linked to AI. Two security researchers used an AI tool to win a “hack-a-thon” contest, earning them a prize of $123,000. The extent to which AI tools will assist attackers to launch hard-to-detect attacks is frightening. The need to identify and defend against around-the-clock cyberattacks that target all businesses large and small has created an essential workforce that is now at the very core of the information technology (IT) industry. Known as information security, these professionals are focused on protecting electronic information. The demand for these certified professionals in information security has never been higher. However, a large gap remains. Although the global cybersecurity workforce grew to 4.7 million workers in 2021, reaching its highest-ever levels, there is still a need for more than 3.4 million security professionals, an increase of over 26 percent from the prior year. When filling cybersecurity positions, an overwhelming majority of enterprises use the Computing Technology Industry Association (CompTIA) Security1 certification to verify security competency. Of the hundreds of security certifications currently available, Security1 is one of the most widely acclaimed security certifications. Because it is internationally recognized as validating a foundation level of security skills and knowledge, the Security1 certification has become the foundation for today’s IT security professionals. The value for an IT professional who holds a CompTIA security certification is significant. On average, an employee with a CompTIA certification commands a salary between 5 and 15 percent higher than their counterparts with similar qualifications but lacking a certification. The CompTIA Security1 certification is a vendor-neutral credential that requires passing the current certification exam SY0-701. A successful candidate has the knowledge and skills required to identify attacks, threats, and vulnerabilities; design a strong security architecture; implement security controls; be knowledgeable of security operations and incident response; and be well versed in governance, risk, and compliance requirements. Certification provides job applicants with more than just a competitive edge over their noncertified counterparts competing for the same IT positions. Some institutions of higher education grant college credit to students who successfully pass certification exams, moving them further along in their degree programs. For those already employed, achieving a new certification increases job effectiveness, which opens doors for advancement and job security. Certification also gives individuals who are interested in careers in the military the ability to move into higher positions more quickly. CompTIA® Security1 Guide to Network Security Fundamentals, Eighth Edition, is intended to equip learners with the knowledge and skills needed to be information security IT professionals. Yet it is more than an “exam prep” book. While teaching the fundamentals of information security by using the CompTIA Security1 exam objectives as its framework, the book takes a comprehensive view of security by examining in depth today’s attacks against networks and endpoints and what is needed to defend against these attacks. This book is a valuable tool for those who want to learn about information security and enter the field. It also provides the foundation that will help prepare for the CompTIA Security1 certification exam. For more information on CompTIA Security1 certification, visit CompTIA’s website at comptia.org.
