Attacker Lauren has gained the credentials of an organization's internal server system, and she was often logging in during irregular times to monitor the network activities. The organization was skeptical about the login times and appointed security professional Robert to determine the issue. Robert analyzed the compromised device to find incident details such as the type of attack, its severity, target, impact, method of propagation, and vulnerabilities exploited. What is the incident handling and response (IH&R) phase, in which Robert has determined these issues?
Correct Answer:
D
Triage is that the initial post-detection incident response method any responder can execute to open an event or false positive. Structuring an efficient and correct triage method can reduce analyst fatigue, reduce time to reply to and right incidents, and ensure that solely valid alerts are promoted to “investigation or incident” status.
Every part of the triage method should be performed with urgency, as each second counts once in the inside of a crisis. However, triage responders face the intense challenge of filtering an unwieldy input supply into a condensed trickle of events. Here are some suggestions for expediting analysis before knowledge is validated: Organization: reduce redundant analysis by developing a workflow that may assign tasks to responders.
Avoid sharing an email box or email alias between multiple responders. Instead use a workflow tool, like those in security orchestration, automation, and response (SOAR) solutions, to assign tasks. Implement a method to re-assign or reject tasks that are out of scope for triage. Correlation: Use a tool like a security info and even management (SIEM) to mix similar events. Link potentially connected events into one useful event.
Data Enrichment: automate common queries your responders perform daily, like reverse DNS lookups, threat intelligence lookups, and IP/domain mapping. Add this knowledge to the event record or make it simply accessible.
Moving full speed ahead is that the thanks to get through the initial sorting method however a a lot of detailed, measured approach is necessary throughout event verification. Presenting a robust case to be accurately evaluated by your security operations center (SOC) or cyber incident response team (CIRT) analysts is key. Here are many tips for the verification: Adjacent Data: Check the data adjacent to the event. for example, if an end has a virus signature hit, look to visualize if there’s proof the virus is running before career for more response metrics.
Intelligence Review: understand the context around the intelligence. simply because an ip address was flagged as a part of a botnet last week doesn’t mean it still is an element of a botnet today.
Initial Priority: Align with operational incident priorities and classify incidents appropriately. ensure the
right level of effort is applied to every incident. Cross Analysis: look for and analyze potentially shared keys, like science addresses or domain names, across multiple knowledge sources for higher knowledge acurity.
Which of the following options represents a conceptual characteristic of an anomaly-based IDS over a signature-based IDS?
Correct Answer:
B
Steve, an attacker, created a fake profile on a social media website and sent a request to Stella. Stella was enthralled by Steve's profile picture and the description given for his profile, and she initiated a conversation with him soon after accepting the request. After a few days. Sieve started asking about her company details and eventually gathered all the essential information regarding her company. What is the social engineering technique Steve employed in the above scenario?
Correct Answer:
C
The honey trap is a technique where an attacker targets a person online by pretending to be an
attractive person and then begins a fake online relationship to obtain confidential information about the target company. In this technique, the victim is an insider who possesses critical information about the target organization.
Baiting is a technique in which attackers offer end users something alluring in exchange for important information such as login details and other sensitive data. This technique relies on the curiosity and greed of the end-users. Attackers perform this technique by leaving a physical device such as a USB flash drive containing malicious files in locations where people can easily find them, such as parking lots, elevators, and bathrooms. This physical device is labeled with a legitimate company's logo, thereby tricking end-users into trusting it and opening it on their systems. Once the victim connects and opens the device, a malicious file downloads. It infects the system and allows the attacker to take control.
For example, an attacker leaves some bait in the form of a USB drive in the elevator with the label "Employee Salary Information 2019" and a legitimate company's logo. Out of curiosity and greed, the victim picks up the device and opens it up on their system, which downloads the bait. Once the bait is downloaded, a piece of malicious software installs on the victim's system, giving the attacker access.
A post-breach forensic investigation revealed that a known vulnerability in Apache Struts was to blame for the Equifax data breach that affected 143 million customers. A fix was available from the software vendor for several months prior 10 the Intrusion. This Is likely a failure in which of the following security processes?
Correct Answer:
D
Patch management is that the method that helps acquire, test and install multiple patches (code changes) on existing applications and software tools on a pc, enabling systems to remain updated on existing patches and determining that patches are the suitable ones. Managing patches so becomes simple and simple.
Patch Management is usually done by software system firms as a part of their internal efforts to mend problems with the various versions of software system programs and also to assist analyze existing software system programs and discover any potential lack of security features or different upgrades.
Software patches help fix those problems that exist and are detected solely once the software’s initial unharness. Patches mostly concern security while there are some patches that concern the particular practicality of programs as well.
A hacker is an intelligent individual with excellent computer skills and the ability to explore a computer’s software and hardware without the owner’s permission. Their intention can either be to simply gain knowledge or to illegally make changes.
