Excellent point about obtaining visibility
  1. What are the most common successful attack vectors for my type of company and environment?
    • Email, Web, RDP and SSH
  2. How likely would we be to detect such an attack should it occur?
    • Extremely likely, we review logs everyday on external systems, we have SIEM, HIDS, NIDS monitoring essential and non-essential systems, notifications are sent and collected using Logwatch | crontab provides extensive information
  3. Can we make this type of attack harder and more expensive for the hacker?
    • Yes, using Web (NGFW, place in DMZ) and Email (Proofpoint)
    • RDP - use hardening mechanisms provided by DISA Stigs, only allow local subnets
    • SSH - use keys, remove root access, only allow certain ranges of IP to access systems
    • IPv6 - implement IPv6 and move off of IPv4 (most attacks come from IPv4, we have identified that on our AWS and GCP servers), configure VPN ESP/AH AES256 IPSec tunnels
    • Utilize cloud service to monitor servers and access
    • Countries that are not relevant to the business remove access, insert rules to block countries (PaloAlto, SonicWall, Juniper, and others do a good job), but also employ the blocking mechanism on outbound ACLs
    • Encrypt data at rest and in transit, utilize IPSec from IPv6
    • Configure MPLS VPN rd1:1 connections to remote sites, think about IS-IS configuration for remote connections, think about Route Bridges and TRILL, move away from OSPF (no self-healing properties)

This is what I can think about off the top of my head, other items will come.

PUBLISHED: 2020-02-28
In Puma (RubyGem) before 4.3.2 and 3.12.2, if an application using Puma allows untrusted input in a response header, an attacker can use newline characters (i.e. `CR`, `LF` or`/r`, `/n`) to end the header and inject malicious content, such as additional headers or an entirely new response body. This...
