A couple of ideas on the safety bulletins to this point at AWS re:Invent
Extra AWS Safety Posts
On this submit I am simply compiling among the safety bulletins in AWS re:Invent. I am going to have to return and take a more in-depth take a look at them later as sadly and thankfully somebody employed me to show a category throughout re:Invent.
I am undecided once I’ll be talking at a big convention once more, however I attempt to sustain with what individuals are speaking about primarily based on what data I discover on-line. Lately I are likely to prioritize what drives the enterprise and makes cash to be trustworthy as I journey much less. However I actually miss seeing my buddies at re:Invent!
This is my preliminary response to the advertisements, however once more, with out all the main points and it is a lady’s prerogative to vary her thoughts. 🙂
Safe community entry with out VPN to company purposes
Many options are taking completely different approaches to distant entry. There are numerous options that attempt to join folks on the software layer, slightly than the community layer within the OSI mannequin. Some are fascinating, others not a lot. With out diving into the answer, that is what you need to ask:
- If somebody will get your credentials or an energetic session, can they use them from an alternate community location to get to the host the place you are lastly related and dealing? If that’s the case, it is an identification resolution, not a community resolution.
- Does the encryption used to connect with the distant host encrypt all people community site visitors to the distant host or simply site visitors on a specific protocol? As I’ve written earlier than, some VPNs are higher than others in that regard (SSL vs. IPSEC).
- Does the answer permit you to examine all community site visitors (accepted, rejected, or failed) on all ports between the distant host and the vacation spot endpoint?
- Are you able to see the entire packages? Some assaults under the applying layer within the OSI mannequin is probably not seen if you cannot see all the main points of the community packets, as I defined in different posts.
- When somebody connects to the distant endpoint, can others entry that distant endpoint over the Web? Whenever you hook up with a VPN, the VPN endpoint is uncovered, however there are not any hosts contained in the community in case you are not related to the VPN. I as soon as ran a penetration take a look at the place one of many objectives was to see if the bastion host was susceptible. Basically, I reverse engineered the truth that the bastion host was behind a VPN, so the one manner it could be susceptible is that if it might get by means of the VPN first. That’s what a VPN does for you. When hosts are immediately uncovered to the Web with none layers between them, they’re open to direct assault from the Web.
- Are you able to handle all entry from one level or do it’s a must to individually handle each host uncovered to the Web for distant entry? If you cannot handle them centrally, you’ve got exponentially elevated administration and danger. Errors and misconfigurations accounted for 13% of safety incidents within the 2022 Verizon Information Breach Report, so that you need to scale back the possibility of misconfiguration by lowering what it’s a must to handle. A VPN does that (as does the automation I wrote about right here for per-user cases that use a single script for deployment to some extent – there are tradeoffs to that strategy vs. VPN, but it surely’s higher than exposing each host to the Web). I assume this new service is a centralized resolution, however I have never regarded into it.
If this new resolution meets the entire above standards, then it may be a VPN alternative. More often than not, when firms promote an answer as a VPN alternative, they’re really not, however maybe Amazon has cracked the nut with this new service.
When it comes to new app-based safety approaches, one cool factor about them is that when somebody connects to an app, they can not “scan the community” within the conventional sense with a instrument like nmap. I have never inspected this but to see if it is that type of resolution or one thing else.
This seems to be very fascinating if it might probably assist arrange a zero belief community for service to service communication. I have been writing about serverless networking in my newest weblog collection on automating cybersecurity metrics and this service can assist. I am going to should test it out. For folks simply beginning to construct purposes, serverless is simpler than all of the configuration it’s a must to do to arrange Kubernetes and even EC2. Associated networks, not a lot. Possibly this may assist.
Once more, you will need to test that it meets the identical community necessities because the VPN above to find out if it is really a community resolution or an identification resolution.
AWS KMS Exterior Key Retailer
This service seems to be nice for organizations that must host keys on premises however need to combine with KMS. Typically clients need to management their very own key or want the important thing to be accessible on a non-public community and on AWS (though I would not be too excited in regards to the potential latency in that case). This can assist some bigger organizations with compliance constraints or excessive safety wants.
AWS Inspector: Lambda Vulnerability Scan
Superior. You will want to check out the actual programming languages and vulnerabilities you discover, however that is nice information! I’ll positively attempt it.
Automated Information Discovery for Macie
Macie needs that can assist you discover the place automated information exists that you just won’t pay attention to in S3 buckets. As with information exfiltration instruments, I assume this may must be monitored and tuned for false positives. Information exfiltration and the identification of delicate information is all the time a problem. Burp typically identifies random strings corresponding to bank cards, for instance, in penetration assessments that aren’t really bank cards. He could also be ready to speculate the assets to handle this instrument, but it surely ought to have the opportunity that can assist you discover your delicate information and lock it down.
Permissions verified by Amazon
Amazon calls this new function:
a scalable and granular permission administration and authorization service for customized purposes
If it is what I believe it’s, I as soon as wrote one thing like this. We had a central automation service that might learn the configuration information and permit or deny actions primarily based on the configuration information written by the builders. The builders didn’t have to put in writing the code to authorize actions, however slightly outline the actions allowed for a specific sort of person.
It additionally sounds much like Open Coverage Agent (OPA) which got here out later and is an idea I actually like. I am going to should attempt it out to see if it is what it seems to be like.
Automated failback on AWS for AWS Elastic Catastrophe Restoration
This new function seems to be fascinating. We should see if it helps with Ransomware.
Backup for CloudFormation stacks
This additionally seems to be fairly fascinating. I stay up for attempting this.
Helpful for many who use Redshift to revive when wanted.
New: Failover controls for Amazon S3 multi-region entry factors
One other service to test and take a look at for these creating automated failover within the occasion of an AWS outage or safety incident. When S3 has issues, many purposes have issues. Failover with S3 will be difficult. Hopefully this makes it simpler.
Amazon Safety Lake
Information storage utilizing the OCSF customary. That is positively one thing for safety folks to take a look at who has to take care of all the safety logs in a company. Should you take part within the preview, you might be able to present beneficial suggestions to assist push the modifications in the correct route to satisfy your wants.
Configuration Guidelines — Proactive Enforcement
Proactive is best than reactive. That is positively value trying out. In a single surroundings I labored in, a community compliance instrument would roll again a non-compliant change in three minutes. And that was across the time somebody on the safety crew wanted to open entry to his occasion and make a configuration change that he wanted. After I confronted him about it, he mentioned it was a “dumb instrument”. It wasn’t, but it surely exhibits the necessity to forestall change if potential, slightly than react after it is too late.
Management Tower — Complete Management Administration
Management Tower is a much-needed service, however as I’ve written earlier than, some issues are a bit difficult whenever you’re attempting to make use of and keep it. However the idea is on level and I am excited to see this.
Amazon EventBridge Pipelines
This is not precisely a safety function, but when it helps enhance consistency and reduces complexity by means of abstraction, it might probably assist total safety in a company by connecting providers asynchronously.
Wickr: end-to-end encryption for communication providers
There may be! I used to be in search of extra data on end-to-end encryption in my final Amazon Chime weblog submit. It isn’t clear that the communication is definitely end-to-end encrypted primarily based on the documentation. I am undecided if Amazon Chime makes use of this service or is end-to-end encrypted or not primarily based on what I discovered, but when it must be, this service can assist as a result of it clearly is.
New: Amazon ECS Service Join allows straightforward communication between microservices
This service sounds much like Lattice (above) however for ECS.
CloudWatch Log Information Safety
Appears to detect delicate information in logs. It’s positively value trying out.
CloudWatch cross-account observability
I wrote about some points with cross account registration for KMS. I believe that is going to be a really, very helpful function and I stay up for attempting it out and probably running a blog about it later in my newest weblog collection the place I am constructing a cloud safety structure for batch jobs (and actually the rest). ).
Runtime risk detection of containers on guard obligation
This was introduced on the AWS keynote by Adam Selipsky. I do not see it within the AWS information bulletins but, however I discovered this submit from November.
I wrote about that and another security-related options right here after watching the AWS keynote.
I could have missed one thing and there’s a bit additional to go in AWS re:Invent. I’ll replace this submit if I see something new.
Comply with for updates.
