2018-017- threat models, vuln triage, useless scores, and analysis tools


Vuln mgmt tools CVE scores suck.

 

Threat modeling is good.

 

Forces  you to know your environment

2018-014- Container Security with Jay Beale


 

 

Container security

 

Jay Beale  @inguardians , @jaybeale

 

Containers

  • What the heck is a container?
    • Linux distribution with a kernel
      • Containers run on top of that, sharing the kernel, but not the filesystem
    • Namespaces
      • Mount
      • Network
      • Hostname
      • PID
      • IPC
      • Users
  • Somebody said we’ve had containers since before Docker
    • Containers started in 2005, with OpenVZ
    • Docker was 2013, Kubernetes 2014
  • Image Security
    • CoreOS Clair for vuln scanning images
    • Public repos vs private
    • Don’t keep the image running for so long?
    • Don’t run as root
  • More Containment stuff
    • Non-privileged containers
    • Remap the users, so root in container isn’t root outside
    • Drop root capabilities
    • Seccomp for kernel syscalls
    • AppArmor or SELinux
  • All of above is about Docker, what about Kubernetes
    • Get onto most recent version of K8S - 1.7 and 1.8 brought big security improvements
    • Network policy (egress firewalls)
    • RBAC (define what users and service accounts can do what)
    • Use namespaces per tenant and think hard about multi-tenancy
    • Use the CIS guides for lockdown of K8S and the host
    • Kube-bench

Difference between containers and sandboxing

 

Roll your own -

    Containers

        Using public registries - leave you vulnerable

        Use your own private repos for deploying containers

 

Reduce attack surface

Reduce user access

 

Automation will allow more security to get baked in.

2018-013-Sigma_malware_report, Verizon_DBIR discussion, proper off-boarding of employees


Report from Bsides Nash - Ms. Berlin

New Job

Keynote at Bsides Springfield, MO

Mr. Boettcher talks about Sigma Malware infection.

 

http://www.securitybsides.com/w/page/116970567/BSidesSpfd

**new website upcoming**

Registration is coming and will be updated on next show (hopefully)

DBIR -https://www.verizonenterprise.com/resources/reports/rp_DBIR_2018_Report_execsummary_en_xg.pdf

 

VERIS framework

http://veriscommunity.net/

 

53,000 incidents

 

2,216 breaches?!

 

73% breaches were by outsiders

 

28% involved internal actors (but needs outside help?)

 

Not teaching “don’t click the link”, but instead teach, “I have no curiosity”

   

Discuss "Dir. Infosec" Slack story as method to halt infection

 

https://www.tripwire.com/state-of-security/security-awareness/women-information-security-amanda-berlin/

The “Living off the Land” trend continues with attack groups opting for tried-and-trusted means to infiltrate target organizations. Spear phishing is the number one infection vector employed by 71 percent of organized groups in 2017. The use of zero days continues to fall out of favor.

 

Off boarding people… so much process to get people on, but it’s just not mature getting people out...

2018-012: SIEM tuning, collection, types of SIEM, and do you even need one?


Bryan plays 'stump the experts' with Ms. Berlin and Mr. Boettcher this month...

We discuss SIEM logging, and tuning...

How do SIEM deal with disparate log file types?

What logs should be the first to be gathered?

Is a SIEM even required, or is just a central log repo enough?

Which departments benefit the most from logging? (IT, IR, Compliance?)
