Planing and Scoping<\/span><\/strong> phase, the goal is to define the business needs and understand compliance requirements. With this information, an initial estimation of the (daily) log volume can be calculated. Crucial information for sizing the architecture that will be desinged and implemented within the next steps.<\/p>\n\n\n\nWith the Architecture and Infrastructure Design<\/span><\/strong>, we start defining how the architecture will look like, based on the needs and requirements identified in the previous phase. As you may now, a SIEM platform is made of different type of components, each of them fulfilling different purposes. We can have indexers, collectors, search heads, etc. In this phase we analyze and define how many indexers we will need, how many collectors we will need, where they will be located, what are the hardware and software specification that the systems will have, etc. <\/p>\n\n\n\nWith the Data Ingestion and Pipepline Engineering<\/span><\/strong> phase, we start thinking about from which systems\/assets we want to collect the data and send it to our SIEM. Do we need Active Directory logs? For sure, to properly perform account monitoring and detect potential threats. Do we need Firewall logs? Of course, to detect potential scanning, initial phase of an attack, and understand if somebody is knocking on our door. But do we need all the events from the AD and from the Firewalls? We try to answer all these questions within this phase. <\/p>\n\n\n\nWithin the Parsing and Normalization<\/span><\/strong> phase, we have a closer look to the data that we have decided to ingest in the previous step. With Parsing we refer to the phase related to data extraction from the logs. Is the relevant information being parsed properly as expected? Are the values properly extracted? With Normalization phase we ensure that information that is being extracted is stored and named in a proper way, so that can be found, and used for detection purposes.<\/p>\n\n\n\nWith the Detection Engineering and Use Case Deployment,<\/span><\/strong> we identify what we want threats we want to detect, and we build related detection rules, that leverages the data we decided to ingest in the earliest phases. Do we want to detect brute force attempts on our accounts? do we want to detect outgoing ssh connections toward internet?<\/p>\n\n\n\nWith the Alert Tuning and Noise Reduction<\/span><\/strong> phase we improve our detection rules, we work on reducing false positives, adjusting the thresholds, configuring exceptions, and filtering out unnecessary noise.<\/p>\n\n\n\nNow, we have detection rules, working properly, detecting potential threats, generating alerts, but we do not have the resources (manpower) to handle them within the desired timeframe. Thats why we need to leverage Automation, otherwise our security team will drawn in the sea of alerts, and burnout, and leave the organization. A natural evolution of a mature SIEM, is to pair it with a SOAR solution. SOAR platforms allow to create playbooks, that can take care of different phases of the alert handling process, from triage, to active response, depending on our needs and use cases. That is what we do within the SOAR Integration<\/span><\/strong> phase.<\/p>\n\n\n\nWe have done this in the past, we know what are the pain points, we have learned the hard way, we have invested the time for you. Lets focus on delivering.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

SOAR – Security Orchestration, Automation and Response<\/span>+<\/span><\/button><\/h3>\n\n\n\n\n
As for SIEM, a deployment of a SOAR platform is a long process made of different phases, each of them targeting specific questions, finding answers, and building a tailored solution for the environment. <\/p>\n\n\n\n
Usually a SOAR deployment consists of the following phases:<\/p>\n\n\n\n
\nProcess Standardization<\/li>\n\n\n\n API Integration and Environment Setup<\/li>\n\n\n\n Use Case Selection<\/li>\n\n\n\n Playbook Development & Testing <\/li>\n\n\n\n Deployment<\/li>\n\n\n\n Monitoring<\/li>\n<\/ol>\n\n\n\nSolutions like SOAR need as input working already optimized processes. It cannot automate broken processes. Thats why the first phase is about Process Standardization<\/span><\/strong>. Defining the processes, their structure, decision trees, necessary approvals, etc. Once this is set, we can start looking for the best way to automate it. <\/p>\n\n\n\nOnce we have identifed what process(es) we want to automate, we need to identify which systems are involved in the process. If for example we are trying to automate the account disable process, we will definitely have to deal with the Active Directory. And once the account is disabled we will likely want to update our case with the action taken, etc. Thats why the API Integration and Environment Setup<\/span><\/strong> phase is needed. Now that we know the systems involved in the process, we need to understand the best way to connect them to our SOAR platform. Usually this is done via API, or using service accounts. <\/p>\n\n\n\nAfter we have successfully connected the necessary systems, we need to choose what use case we want to tackle. This is the Use Case Selection<\/span><\/strong> phase. What is the most repetitive, time consuming task that we could automate and save precious time of our analysts? Start with low-hanging fruits. <\/p>\n\n\n\nOkay, we have identified the use case that we want to automate, and now we need to get our hands dirty, and start developing it. We are in the Playbook Development and Testing<\/span><\/strong> phase. We first need to design a high level structure of the SOAR playbook that we want to implement. Its a good practice to start with basic functions, working with “versions”. Once we have a high level structure we start using actions and building blocks to achieve the logic that we need. What we want is a first working and tested version. <\/p>\n\n\n\nWe have finished the implementation, and tested, and we feel confident enough to deploy in production. Thats what we do in the Deployment <\/span><\/strong>phase. We move our playbook from staging\/development to Production. <\/p>\n\n\n\nOnce its in production, we cannot just forget about it. We need to monitor the playbook and notice if any strange behavior is observed. Thats what is for the Monitoring <\/span><\/strong>phase. Its a good practice having a more intense monitoring, for the first weeks, and later to rely on automated monitoring tools.<\/p>\n\n\n\nAnd this high level, and as we all know, the devil its in the details, but no worries, we know how to handle them. <\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n
