How many outbound connections should i have

Being a proxy server, P also acts as a client to S. Every S has a unique IP address. It appears to me that outbound connections should work exactly the same as inbound connections, namely: a connection is identified by the aforementioned 4-tuple, and since every S has a unique IP address, setting up However, I am finding conflicting information: Some sources make it appear as though outbound connections work differently from inbound connections, in that for outbound connections the local ip and port combination must be unique, so I will run out of ephemeral ports after max.

This seams like a strange asymmetry between inbound and outbound connections to me. The proposed solution here is to use multiple IP addresses for outbound connections. Is my understanding that there is an asymmetry correct? And if so, why is that? And is there a way to overcome the outbound connection limitation?

If it is of any influence on possible solutions: The proxy will be deployed to Azure. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Collectives on Stack Overflow. Learn more.

Ask Question. Asked 10 months ago. The key is to always catch and alert on anything outside the ordinary whatever that means for your organization. To monitor inbound connections based on the location of users , admins should monitor the origin of IP addresses and cordon off any that come from unexpected or inappropriate locations using AWS Security Groups.

This way, you are likely to catch account compromises early on, before malicious actors have a chance to breach your systems and do damage. IPs cordoned off by security groups in error can always be reviewed and approved later, but again: better safe than sorry. To block known-bad IPs , use threat intelligence to identify bad IP addresses and investigate any attempted inbound connections coming from them.

This will cut down on the spread of malware, for example, by identifying attempted attacks early on and preventing them from successfully breaching your network. Outbound connections are a bit more complex. For example, package repositories like Ubuntu are hosted all around the world. To keep the cloud environment safe, SecOps teams need to monitor and alert on outbound connection attempts like these.

Origin of Outbound Connections: The best way to know when something goes wrong is to know what it looks like when everything is going well. To do this, build a model that shows what normal, everyday traffic looks like. This will make it much easier to visualize and catch when something deviates from the norm and indicates possible compromise.

Known-Bad Actors: To track outbound connections, you need the ability to detect when a connection is attempted from inside your network to a known-bad actor website domains known to be affiliated with malicious activity. SecOps teams need to know when a process connects to a known-bad site from a node. Your goal is to be able to identify this activity by knowing the bad actors e.
