3、 wild ride,with dizzying changes in the way we live and work as we navigate enormous unpredictability brought on by a global pandemic,among other world events.For organizations,digital transformation has gone from priority to urgent imperative,and nearly every company has become a technology company

4、 out of necessity.But necessity is also the mother of invention.These unprecedented and volatile times have pushed us to innovate at lightning speed.Whats fueling the most critical innovations?Accelerated cloud technologies and the power of data.To not only survive but thrive in this hybrid world,or

5、ganizations need solutions that are powerful,flexible and fast solutions powered by data.With a strong data and technology foundation,organizations can respond quickly to whatever comes their way,secure their organizations from ever-evolving threats and use their data to innovate.But not every organ

6、ization has been able to tap the power of data,due to three major challenges:Data silos:With too many tools within and across teams,data is often fragmented and hard to see,which leads to inefficiency and vulnerabilities.Lack of visibility across processes:Without contextual data,its difficult to tr

7、ack business processes end to end,making it harder to get to root causes and find ways to optimize.Security and compliance regulations:Constantly changing security,privacy and compliance regulations make it even more challenging to make sure the right data is accessed at the right time,with the righ

8、t governance.As a consequence,organizations have difficulty drawing insights from and taking action on their data.Its just too time consuming and resource intensive.But theres a solution:your organization can meet these challenges,stay secure and tap the power of data by employing the right security

9、 information event management(SIEM)solution,one thats cloud-based and data-driven.A SIEM solution is like a pilots radar system.Like pilots,the analysts who help pilot your security operation center(SOC)need radar to safely navigate whats around them,whats ahead and what might be hidden out of view.

10、A SIEM solution is a security platform that helps SOC analysts see across enterprise IT and spot security threats hiding in the corners of the systems they protect.Without it,theyre flying blind.While security applications and network security and system software do catch and log isolated attacks an

11、d anomalous behavior,todays most serious threats are distributed and cant be caught with these tools alone.Hackers attack in unison across multiple systems and use advanced evasion techniques to avoid detection.Attackers also take advantage of stressful situations to exploit weaknesses situations li

12、ke,say,an immediate shift to remote work during a global pandemic.In the middle of that urgent transition,SOC teams were tasked with keeping systems secure,but without in-person access to the security tools and processes theyd come to rely on.Situations like these are why a modern SIEM solution is m

13、ore important than ever.Without the right SIEM,cyberattacks can fester and turn into catastrophic incidents that even the best SOC analysts cant see coming.And by the time they discover the vulnerability like a ransomware or supply chain attack all they can do is damage control and start the search

14、for a new CISO.In this buyers guide,well take a deep dive into what exactly a SIEM solution is,what it does,how its different from other tools,and how to find the right SIEM solution for your organization.The SIEM Buyers Guide|Splunk3Whats a SIEM?What does a SIEM do,exactly?Gartner defines a SIEM so

15、lution as“a technology that supports threat detection and security incident response through the real-time collection and historical analysis of security events from a wide variety of event and contextual data sources.”Basically,a SIEM solution helps SOC analysts do their jobs better.Its a security

16、platform that ingests event logs and gives them a single view of their data,with more insight.With a modern SIEM,analysts can solve three major security challenges:A lack of visibility into the real-time status of your organizations security often referred to as security posture.Trying to reduce the

17、 amount of false positive security alerts analysts see,prioritizing them,and then increasing the speed of their detections and investigations.A lack of flexibility or support for different types of deployment environments,technology tools and threat intelligence.So how are organizations trying to so

18、lve those challenges today without a SIEM solution?Historically,theyve used“legacy”solutions,various point solutions,and more recent emerging tools like extended detection and response(XDR)solutions.Lets explore what all those are,and the pros and cons of each quickly.Legacy SIEMs are dinosaursOkay,

19、not literally,but legacy SIEM technology is now over a decade old,and legacy SIEMs just arent built to keep up with todays evolving security challenges.With a closed environment and limited data they can ingest,theyre slow at queries and investigations,and they dont scale to meet business needs.Many

20、 enterprise IT organizations that invested in SIEM platforms discovered this the hard way.They learned after spending a lot of money that it takes a long time to ingest all their data into a legacy SIEM,and that the underlying data system used to create the SIEM tends to be static.Though there are a

21、 myriad of software options on the market for collecting,storing and analyzing security-only data,only a few can turn that data into actionable intelligence,and a legacy SIEM isnt one of them.Then theres the issue of speed.Your SOC analysts cant afford to lose precious time when there is a security

22、alert,and a legacy SIEM solution cant keep up with the pace at which they need to investigate data.Worse yet,legacy SIEMs can only provide data on security events,which makes it difficult to correlate security events with whats happening across the rest of an IT environment.That might have worked a

23、decade ago,but not in our hybrid world,where some employees work remotely,others bring their own devices to the office,and everything in between is connected and generating data all of which is crucial to security.Especially with todays rapid adoption of cloud services,which continues to expand the

24、threat vectors,todays organizations need to monitor user activity,behavior and application access across key cloud and software-as-a-service(SaaS)solutions,not just on-prem services,to determine the full scope of potential threats and attacks.The SIEM Buyers Guide|Splunk4Seven Reasons to Replace You

25、r Old SIEMOrganizations are often tied to the dated architectures of traditional SIEMs,which typically use an SQL database with a fixed schema.These databases can become a single point of failure or suffer from scale and performance limitations.1.LIMITED SECURITY TYPESBy limiting the type of data th

26、at is ingested,there are limits in detection,investigation and reponse times.2.INABILITY TO EFFECTIVELY INGEST DATAWith legacy SIEMs,the ingestion of data can be a massively laborious process or very expensive.3.SLOW INVESTIGATIONSWith legacy SIEMs,basic actions,such as raw log searches,can take a s

27、ignificant amount of time often many hours and days to complete.4.INSTABILITY AND SCALABILITYThe larger SQL-based databases get,the less stable they become.Customers often suffer from either poor performance or a large number of outages as spikes in events take servers down.5.END-OF-LIFE OR UNCERTAI

28、N ROADMAPAs legacy SIEM vendors change ownership,R&D slows to a crawl.Without continuous investment and innovation,security solutions fail to keep up with the growing threat landscape.6.CLOSED ECOSYSTEMLegacy SIEM vendors often lack the ability to integrate with other tools in the market.Customers a

29、re forced to use what was included in the SIEM or spend more on custom development and professsional services.7.LIMITED TO ON-PREMISESLegacy SIEMS are often limited to on-premises deployments.Security practitioners must be able to use cloud,multicloud,on-premises and hybrid workloads.The SIEM Buyers

30、 Guide|Splunk5What else is out there?The truth is out there But lets start with the truth about point solutions versus platform solutions.Point solution vendors are lying if they tell you they can do what a modern SIEM solution can.They typically do one or two things really well,but without a centra

31、lized way of making sense of an organizations data,SOC analysts are flying blind.Point solutions dont offer that radar system they need to safely navigate whats around them,whats ahead,and whats still unknown.Then you have XDR an emerging solution generating a lot of(marketing)buzz.But you cant alwa

32、ys believe the hype.XDR is an evolution of endpoint detection and response(EDR),which has traditionally served as an additional data source for a SIEM solution not a replacement for it.Though XDR can be used in tandem with a modern SIEM,XDR alone wont cut it.Not being able to see into a companys sec

33、urity posture makes the job of your SOC analyst almost impossible.And the last thing you want to do is make the life of your SOC analyst harder,because there just arent enough good SOC analysts to go around.Lets face it,the eternal security skills shortage has only gotten worse since the pandemic st

34、arted.Going back to that radar system:without visibility,security investigations can only scratch the surface of true incident resolution and that leads to more vulnerabilities down the line.The less visibility your organization has,the more vulnerable it is to a high-profile breach,which can cost m

35、illions of dollars and its reputation.No CEO wants to see their companys name in a Bloomberg headline and no CISO wants to explain why that happened.The evolution of a data-driven SIEMCall it survival of the fittest.With legacy SIEMs stuck in the past,and new-fangled solutions only able to solve par

36、t of the problem,the modern SIEM had to evolve into a robust,analytics-driven solution to keep up with the sophistication and speed of todays attacks.What SOC analysts require today is a simple way to correlate information across all security-relevant data.A solution that enables IT to manage their

37、security posture easily.SOC analysts must be able to anticipate what threats might be lurking and put measures in place to limit the vulnerability of their company in real time.For that,enterprises need a data-centric,modern SIEM solution that gives analysts full visibility into the data being gener

38、ated by their enterprise,one that works with more than just log data and simple correlation rules for data analysis.Leading SIEM solutions now combine long-time storage of event logs with real-time monitoring to provide your team with a holistic understanding of the organizations security posture.Th

40、IEM.So how can you tell if a solution is the real deal?In the Critical Capabilities for Security Information and Event Management report,Gartner highlights the five things a modern SIEM can do that others cant.Five essential capabilities of a modern SIEM1.Collect security event logs and telemetry in

41、 real time for threat detection and compliance use cases.A modern SIEM solution can collect,use and analyze log data from across an ecosystem of teams,tools,peers and partners in accordance with sector-specific mandates around regulatory compliance and reporting,as well as the latest threat detectio

42、n needs.2.Analyze telemetry in real time,over time,to detect attacks and other activities of interest.A modern SIEM can collect,use and analyze all event logs and give a unified view into whats going on across the security stack in real time.This gives IT and security teams the ability to manage eve

43、nt logs from one central location,correlate different events over multiple machines or multiple days,and tie in other data sources like registry changes and ISA Proxy logs for the complete picture.Security practitioners can also audit and report on all event logs from a single place.3.Investigate in

44、cidents to determine their potential severity and impact on a business.It can also determine the severity and likelihood of potential incidents for each issue identified,and use this information to prioritize and inform on corrective actions.4.Report on these activities.A modern SIEM can also genera

45、te reports containing security information about any part of an organizations infrastructure and provide a means for documentation and compliance requirements.5.Store relevant events and logs.And finally,a modern SIEM solution can store historical log data over the long term,which helps analysts mee

47、an use a modern SIEM to implement them):1.Real-time security monitoring and analysisOrganizations need to be able to detect and respond to threats in record time no matter the nature or severity of the attack.But to do this and do it well,security monitoring is a must-have,and luckily,a modern SIEM

48、offers robust,real-time monitoring.How does it work?To pinpoint and identify different types of malicious and/or anomalous behavior,a SIEM retrieves and maintains contextual data around users,devices and applications(e.g.,asset and identity data)from across on-prem,cloud,multicloud and hybrid enviro

49、nments.All relevant data is then fed into a workflow to assess potential risks.By monitoring and ingesting machine data from a diverse set of sources across different types of deployments,security teams have a comprehensive view of potential security events making it that much easier to detect and z

50、ero in on bad actors.A leading SIEM should provide a library of customizable,predefined correlation rules,a security event console for real-time presentation of security incidents,and dashboards to provide real-time visualizations of ongoing threat activity.Security monitoring can also be augmented

51、with out-of-the-box correlation searches that can be invoked in real time or scheduled regularly.These searches can be available via an intuitive user interface that doesnt require analysts or administrators to master a search language.Finally,a modern SIEM will have a local and historical search fu

62、thenticate users within a zero trust network.Innovate and stay in lockstep with customers while remaining secure.Running a secure ecosystemWith a massive surge in demand due to the pandemic,Slack had to make sure its security program was working effectively and with the welcome help of Splunk launch

63、ed a new application programming interface(API),as well as fortified a zero trust network.By integrating an analytics API with Splunk,users had an easier time keeping a finger on the pulse of the organization.The API integration helped customers get the information they needed and for leadership to

64、stay connected.All of Slacks critical applications were sending logging content into Splunk,bringing data into one place,and offering insight into an array of behavioral patterns.Operating in a zero trust network where users are authenticated and authorized also strengthened Slacks security posture.

65、“Splunk is a key part of Slacks ability to operate a zero trust network,”Ryder says.“Because Splunk gives us visibility into all the activity thats happening across all of our cloud services.”“Splunk is how we verify that our security program is operating across our entire fleet and across our corpo

67、ovide a means for tracking,routing and annotating events.How does it work?A SIEM can manually or automatically aggregate events,support third-party systems and vendors(allowing for the easy ingestion of data to and from a diverse set of sources),and provide up-to-date threat intelligence and auto-re

68、sponse capabilities(like playbooks)that preempt or disrupt cyberattacks either right before or right after they emerge.In order to do all of this,a SIEM solution should be the hub around which an incident response workflow is customized and crafted.Since security events have different levels of urge

69、ncy attached to them,potential threats can be identified,categorized and triaged via dashboards,then assigned to analysts for review.By identifying,triaging and auditing notable events based on the fidelity of the threat,a modern SIEM makes the start of the remediation process more reliable,equippin

70、g your teams with the contextual awareness they need to determine next steps.To expand or reduce the scope of their analysis(which can be vast),your SOC analysts can use a SIEM to apply filters to the sea of log data,then place events,actions and annotations into a timeline to see everything thats g

71、oing on.They can then review and codify these timelines as a repeatable kill chain methodology to deal with specific event types.The SIEM Buyers Guide|Splunk104.Threat intelligenceThreat intelligence is another must-have strategy.But threat intelligence is often too noisy,with your security analysts

72、 having to manually curate data to make use of it.With manual input,context gets lost during the investigation process or the data becomes too disparate,while enrichment in playbooks is too clunky.Making it even harder for your analysts,the most valuable security data is often locked inside silos in

73、 and across companies.With more integrations coming online that are generating more data needing to be secured and stored,this problem isnt going away.Fortunately,thanks to the rapidly growing intelligence marketplace,modern SIEM solutions can integrate threat intelligence into every stage of the in

74、cident response flow,as well as across an ecosystem of teams,tools,peers and partners.How does it work?Threat intelligence transforms internal and external sources of security intelligence for informed,actionable automation across ecosystems of teams and tools and helps with intelligence sharing wit

75、h internal and external stakeholders.Your team can preempt attacks and create complex pipelines without ever having to write or maintain scripts in the backend.Threat intelligence comes integrated into most modern SIEM solutions or as cloud-native SaaS that integrates seamlessly with a modern SIEM p

76、latform.The intelligence provided usually includes indicators of compromise(IOCs),adversary tactics,techniques and procedures,alongside additional context for various types of incidents and activities.This makes it much easier to recognize abnormal activities,as your analysts have all the informatio

77、n they need to assess the risks,impact and objectives of an attack no matter how cunning and respond appropriately.Threat intelligence data can be integrated with machine data to create watchlists,correlation rules and queries for better detection and response to attacks.This information can be auto

78、matically correlated with event data and added to dashboard views and reports,or forwarded to devices that can then remediate the vulnerability in question.Transforming Intels security posture with innovations in data intelligenceIntel was burdened with a legacy SIEM that only a handful of experts k

79、new how to use and needed a new strategy for detecting sophisticated attacks encroaching on their environment.This inspired Intels Cyber Intelligence Platform(CIP)a modern,scalable platform built around cutting-edge technologies(like in-stream processing).Intels data could flow from hundreds of data

80、 sources into a Kafka message bus,then into Splunk for context-rich visibility and greater effectiveness throughout the organization.With the help of Splunk,Intel was able to:Speed up data analysis and detection of sophisticated threats.Deliver a collaborative,unified approach to managing cybersecur

81、ity.Deliver additional business value across security operations.ScalingIntelsCyberIntelligencePlatformCIPs results led to additional data sources,new use cases and many more data models.Eventually,use of the platform expanded to teams like vulnerability management,compliance and enforcement,risk ma

82、nagement and beyond,which placed additional demands on the infrastructure while requiring even faster compute and storage.To maximize the platforms performance,Intels security solution architect and engineers needed a deeper understanding of Splunk and Intel technologies.A collaborative Splunk and I

83、ntel team developed a joint reference configuration to help guide CIPs expansion across compute,memory and storage using the latest Intel products and technologies.Splunk and Intel are now sharing their success with IT and security peers,helping others scale their Splunk and Apache Kafka deployments

86、ents based on narrowly defined detections can lead to a high volume of false positives and a lot of extra noise,quickly overwhelming and overburdening anyone on the front lines.Thats why you need a strong incident investigation and forensics strategy powered by a modern SIEM.How does it work?A moder

87、n SIEM visualizes and correlates data by mapping categorized events against a kill chain,or creating heat maps to better support incident investigations by providing important insight into which tactics have been used by an adversary that map to a particular industry framework.Risk attribution can a

88、lso help optimize threat hunting and reduce the volume of alerts thereby increasing true positives while surfacing more sophisticated threats,like low and slow attacks that most correlation searches traditionally miss.This frees up time and resources to home in on actual(often complex)threats,aligni

89、ng operations to industry-standard cybersecurity frameworks.Bottom line:freeing up your analysts to focus on high-value tasks means theyre better positioned to respond quickly and efficiently in the event of a security breach and who wouldnt want that?Plus,your team can make better informed decision

90、s and gather forensics evidence with the comprehensive collaboration and reporting capabilities integral to a modern SIEM investigative workflow.6.Advanced and insider threat detectionSecurity threats continue to evolve,mutate and find ways to evade standard security procedures and the more sophisti

91、cated the attack,the harder it is for your team to detect and remediate it.Between the changing threat landscape and the crafty nature of new and emerging threats,advanced and insider threat detection strategy has never been more important.Most traditional security tools cant meet the challenge.They

92、 rely on existing rulesets and signatures,and can only detect straightforward,well-known threats,so they fail to address the complexity of advanced security threats,like insider threats,zero-day attacks,laterally moving malware and compromised accounts.How does it work?Fortunately,a modern SIEM can

93、adapt to these threats by stitching together anomalies and correlating them as part of the incident response workflow,as well as implementing capabilities like endpoint detection and behavioral analytics.By establishing multi-dimensional behavior baselines and dynamic peer group analysis ideally in

94、tandem with unsupervised machine learning compromised or misused accounts can be detected.The goal is to not only detect hidden threats,but also determine the scope of the attack and how best to contain it.For this,your team requires real-time views and reporting capabilities that can be extended to

95、 include any number of third-party applications and services.This type of analytics and behavior profiling in a SIEM can exponentially improve detection success,freeing up your teams time and resources to focus on complex,high-fidelity threats,before its too late.The SIEM Buyers Guide|Splunk127.Comp
