Safety provider edge (SSE) generation used to be created to offer protection to faraway and department customers with a unified, cloud-delivered safety stack. To know how SSE answers offer protection to organizations and their customers, it’s profitable to research attacker methods, in addition to the protections and controls SSE answers use to disrupt them.
It’s helpful to make use of the MITRE ATT&CK framework. MITRE ATT&CK is a huge knowledgebase of attacker methods that cybersecurity professionals use to explain the assault kill chains noticed, when learning danger task. This publish goes to make use of the Mitre ATT&CK framework to research explicit methods inside the “lateral motion” class, describe how each and every methodology works, and element how Cisco’s SSE answer, Cisco Safe Get admission to, can offer protection to you from them.
Lateral Motion
Lateral motion is a important segment within the cyber kill chain. As soon as attackers have breached a unmarried machine or consumer account, they want to enlarge their presence inside the community to get admission to precious assets, delicate information, or extra permissive privileges. Lateral motion permits attackers to determine a foothold inside the community, enlarge their achieve, and succeed in their targets.
Attackers use plenty of methods, akin to exploiting faraway services and products or infecting shared assets, to transport horizontally around the community and achieve unauthorized get admission to to extra important techniques or privileged accounts. Through maneuvering laterally, attackers can evade detection, take care of endurance, and maximize the affect in their assault.
In its Endeavor Matrix, the Mitre ATT&CK framework describes lateral motion as a class made up of 9 methods, a number of with a lot of sub-techniques. Whilst this is an excessive amount of to hide on this weblog publish, let’s analyze some of the maximum commonplace methods.
Exploitation of Far off Products and services
One of the crucial key methods utilized in lateral motion is the exploitation of faraway services and products. On this methodology, attackers are searching for a susceptible or misconfigured provider that they may be able to exploit to realize get admission to to the machine it’s operating on. From there, they are going to proceed to milk the faraway machine, incessantly setting up endurance so they may be able to go back to the machine again and again and use it as launchpad to pivot deeper into the community.
Attackers most often get started with finding what services and products are operating on an organization’s faraway techniques, they usually use plenty of discovery methods to decide if any of them are at risk of compromise. Maximum services and products have had some kind of vulnerability someday, and if any of them are left unpatched and out of date, that vulnerability could also be energetic. As an example, in 2017, the WannaCry ransomware used an exploit referred to as EternalBlue, which took benefit of a vulnerability within the server message block (SMB) protocol, to unfold world wide. As well as, programs that can be used within the inside community, akin to MySQL, would possibly comprise vulnerabilities that attackers can exploit. Whilst many of those vulnerabilities could have patches to be had for them, oftentimes it’s tough to patch a useful resource or simple to omit it, leaving them at risk of assaults.
Far off Products and services
Once in a while, the attacker doesn’t want to assault the faraway provider itself, however as a substitute, they may be able to use legitimate credentials which have been stolen every other solution to make the most of faraway services and products meant for staff. On this assault, the attacker obtains stolen credentials thru methods akin to phishing or credential stuffing.
As soon as they have got those credentials, they may be able to use faraway get admission to services and products akin to protected shell (SSH) or faraway desktop protocol (RDP) to transport deeper into the community. Once in a while those credentials are utilized in centralized identification control with unmarried sign-on, which supplies the attacker vast achieve within the community if they may be able to effectively authenticate with the central identification supplier.
In some instances, official programs would possibly make the most of faraway services and products, akin to instrument deployment gear or local faraway desktop programs, which will on occasion be abused to procure faraway code execution or lateral motion.
Taint Shared Content material
Attackers would possibly achieve get admission to to a shared useful resource, akin to a shared garage location like a cloud garage supplier. In those instances, attackers can leverage this get admission to to inject malicious techniques, scripts, or exploit code to another way official recordsdata. When a consumer accesses the contaminated shared content material, the malicious payload executes, giving the adversary get admission to to the faraway machine, permitting to transport laterally deeper into the community.
As an example, in April 2023, Google’s Cybersecurity Motion Group described a upward thrust in danger actors the use of Google Pressure to ship malware and exfiltrate information. The record detailed a geographical region assault that used to be handing over an ISO record containing a malicious DLL by the use of Google Pressure. Some other danger actor saved malware on Google Pressure to evade detection and despatched phishing emails that contained hyperlinks to the malicious record. But any other danger actor used Google Pressure as location to exfiltrate information to.
How Cisco Safe Get admission to Can Lend a hand
Lateral motion is significant element of the cyber kill chain. Correctly addressing lateral motion calls for a mix of danger detection and coverage enforcement. One of the crucial demanding situations organizations face when fighting lateral motion, or cyberattacks on the whole, is the excessive selection of faraway customers. Up to now, organizations trusted digital personal networks (VPNs) to allow faraway customers to get admission to personal corporate assets and to browse the Web with the security of company safety.
There are a couple of demanding situations to depending so closely on VPNs. For one, maximum firms constructed their VPN structure to serve a small minority of customers. As faraway and hybrid paintings was not unusual, customers stretched the capability of VPNs, incessantly resulting in efficiency issues. This leads customers to disconnect from VPNs the place imaginable simply to stick productive, which jeopardizes safety.
The opposite downside is 0 agree with get admission to insurance policies on VPNs are tough, incessantly requiring managing huge and sophisticated get admission to keep watch over lists. This has resulted in a state of affairs the place many firms don’t phase VPN site visitors in any respect. Which means that as soon as an attacker positive aspects get admission to to a company VPN, they may be able to transfer laterally all through the community with relative ease. Lately, this has been an element of a number of high-profile breaches.
Cisco Safe Get admission to used to be designed to offer protection to faraway customers, anyplace they’re and no matter they’re gaining access to, and to protected company assets that should now be available over the Web.
This comes to hanging personal apps in the back of a layer of coverage the use of 0 Accept as true with Community Get admission to (ZTNA). This generation puts a safety boundary round your programs, and, because the identify implies, applies 0 agree with get admission to insurance policies to any consumer making an attempt to connect with the safe useful resource. Those insurance policies may also be so simple as making sure a consumer is authenticated with MFA to posture tests, akin to making sure they’re the use of an up to date running machine or a corporate-managed instrument. It additionally helps logical crew insurance policies, akin to making sure simplest engineers can get admission to code repositories or simplest gross sales and fortify can get admission to buyer courting control answers.
Those insurance policies are implemented on a per-user and per-application foundation, which creates segmentation between programs. That is important in fighting lateral motion. If an attacker manages to circumvent authentication and all get admission to insurance policies, their achieve is proscribed simplest to that software. They’re not able to pivot deeper into the community.
ZTNA isn’t the correct selection for each and every software, which is why Cisco Safe Get admission to additionally makes use of an built-in VPN-as-a-service (VPNaaS) for an entire 0 Accept as true with Get admission to answer. This permits organizations to transport off bodily VPN infrastructure, making improvements to efficiency for finish customers and decreasing control complications. It is usually absolutely built-in into Cisco Safe Get admission to’ unified coverage control, making sure there may be nonetheless segmentation and nil agree with coverage enforcement.
As well as, Safe Get admission to comprises an built-in Firewall-as-a-service (FWaaS) with an intrusion prevention machine. This saves site visitors over non-web protocols and blocks vulnerabilities akin to the ones utilized by WannaCry ransomware.
The opposite a part of fighting lateral motion is obstructing preliminary get admission to by means of protective the consumer when they’re browsing the Web. That is performed by means of blocking off phishing web pages, blocking off malware, and imposing information loss prevention insurance policies. This a great deal decreases the chance the consumer’s account or gadget will turn into compromised, which will save you attackers from ever attending to the lateral motion segment of the kill chain.
Cisco Safe Get admission to cancan ship a lot of these results and functions by means of unifying twelve other safety applied sciences right into a unmarried, unified, cloud-delivered platform. That is referred to as a safety provider edge (SSE) answer. At its core, an SSE answer supplies protected get admission to to the Web, cloud services and products, and personal programs for customers, without reference to the place they’re positioned. It delivers 0 agree with get admission to keep watch over, danger coverage, information safety, and applicable use coverage enforcement for all customers and assets. SSE is the protection element of the protected get admission to provider edge (SASE) structure, which mixes networking and safety to streamline operations, build up safety resilience, supply end-to-end coverage, and securely attach customers to assets.
Cisco Safe Get admission to supplies a greater revel in for finish customers by means of simplifying get admission to flows. Customers now not want to concern about managing VPN connections. When they are trying to get admission to programs, it simply works. It additionally makes IT control more straightforward. It makes use of a unmarried, unified coverage control dashboard for all its element portions. Finally, it makes everybody more secure by means of leveraging complex safety functions to mitigate chance.
