Endpoint SOC and Telemetry Correlation in Today’s Security Environment

In today’s security environment, you must have Endpoint SOC and telemetry correlation as part of your security posture. Particularly when you think about SOC-as-a-Service, about renting infrastructure like firewalls, servers and routers to up your defense game. Let’s take a look at some of the key areas of one view: telemetry agents, data ingestion, correlation rules, and threat hunting.

Telemetry Agents

First up, telemetry agents. Those are lightweight programs, such as those installed on so-called endpoints — computers, laptops, mobile devices. They gather useful metadata, for example process execution activity, network connections, files changes, and user activities. It all depends on how granular the telemetry is that provides the view into endpoint health and security.

The agents are relaying information to the SOC platform at all times making it possible to monitor activities in real time. Telemetry agents when you lease firewalls and servers through your SOC service, these literally plug and play so no expensive hardware sitting on premises not being used.

Advantages of telemetry agents when it comes to SOC rentals:

• Do not affect the performance of endpoints
• The unified SOC receives and stores data from a single source
• Support for devices that are rented such as routers that provides full view into network

Data Ingestion

Next, data ingestion. It is the mechanism through which all raw telemetry is ingested into the SOC-as-a-Service platform. Without good ingestion, telemetry is just all noise.

Data ingestion in SOC as a service rentals: Important points relevant to data ingestion.

• It needs to process data in large scale from multiple telemetry agents in endpoints
• Fast threat detection depends on real-time ingestion of events
• Leasing of scalable infrastructure such as high-end servers can increase data ingest to accommodate rising data loads

With the rental model, this lets you skip the upfront capital cost of hardware — and you can add capacity to your SOC (or scale down) based on your business demands. If your business grows, simply grow your rented infrastructure.

Correlation Rules

Endpoint telemetry analysis is based on correlation rules. They connect all the suspicious data points from disparate places to make useful alerts.

Imagine these rules as digital Dick Tracys, searching for telltale patterns that signify a cyberthreat. Examples include:

• A series of unsuccessful login attempt and the following successful one in a short time interval.
• Peculiar and abnormal file transfers in association with anomalous network traffic
• Spawning of endpoint processes that is consistent with known malware behavior.

Operationalizing these rules is less of a headache in a SOC rental model because, typically, your SOC provider takes care of adding them and managing them. You get access to correlation logic curated by the best in the business, without having to hire personal experts into your staff or buy custom licenses.

Key advantages:

• Quick response times thanks to automated detection
• Fewer false positives as rules are constantly being sharpened
• Consolidated analysis from endpoint to network via leased firewalls and routers

Threat Hunting

And, at the end, threat hunting draw everything together by allowing the proactive investigation.

Using telemetry that is correlated, security analysts are looking for needles in haystacks that automated tools are likely to overlook, particularly in the sophisticated attack landscape of today, where attackers are waging their campaigns via stealth.

In a SOC-as-a-rental model, threat hunter are included as well and as a service:

• Access to experienced hunters of threats
• Advanced analytics tools built-in to rented servers
• Dashboards that provide SOC visibility into endpoint and network telemetry in one place

Proactive threat hunting truncates the chances of the unnoticed breach and a devastating attack. It’s the final layer of defense, and renting your infrastructure means you can use the newest tech and get expert help without buying it all yourself.

Wrapping Up

In conclusion, endpoint telemetry and SOC rentals represent an integrated visibility strategy which is robust and versatile. Telemetry agents gather deep endpoint data, data ingestion pipelines ingest, enrich and route the info, correlation rules turn the data into actionable alerts, and threat hunting uncovers hidden dangers.

Renting firewalls, servers, and routers, allows businesses to have the most advanced SOC capabilities without heavy initial costs. This scales well with our requirements in terms of data and also adds a layer of security by sharing telemetry correlation all-over.

Okay, wasn’t that answer comforting? For businesses that are heavily invested in cybersecurity, using endpoint SOC alongside telemetry correlation via SOC rentals is not just clever, it’s the key to solid, unified visibility across your IT infrastructure.
