BALUG meeting TUESDAY!: Tu 2018-05-15 (Security ...)
This month, for our 2018-05-15 (3rd Tuesday) BALUG meeting:

We don't have a formal presentation lined up for this meeting, but we
do have a suggested discussion topic: Security ...  And more
specifically - we have at least one relative expert and a more specific
area of Security. Most notably: Security for developers from a Linux
sysadmin perspective. Notably:
o On security, most of developers' focus is often on their code itself,
   and with little attention to the broader scope/context
o Security for sysadmins is a topic often rather well covered by
   sysadmins (and others) for sysadmins
o Developers (and software architects, etc.) often can greatly improve
   security by learning from the perspective of sysadmins, e.g.:
o Least Privilege Principle[1] and Defense in Depth[2], notably
   including use of:
   o users, groups, permissions
   o Set Group ID (SGID) - including directories
   o Set User ID (SUID)
   o sudo(8) and secure use thereof (specifying, etc.)
   o Sticky Bit - notably on directories
   o chroot, BSD "jail", containers/Docker, etc.
   o ssh-keys: authorized_keys and restricting commands, source IPs, etc.
   o Kerberos[3]
   o passwords, salts[4], hashes[5], pepper[6]
   o various authentication means - less secure and more so
   o encryption; secure data storage
   o trust relationships
   o data validation
   o code review, security review, pair programming
   o scanning, testing, top vulnerabilities in/from developer realm
   o etc.

     splitting up the check.  One can also specifically order the

BALUG meeting 2018-06-19: Elizabeth K. Joseph: DC/OS

For our 2018-06-19 meeting we are proud to present:

Elizabeth K. Joseph[1]: DC/OS (the datacenter operating system)[2]

Elizabeth K. Joseph joins us to give an introduction to DC/OS.

Tooling around container orchestration has gained a lot of attention
recently with various open source tools promising to deliver the
framework to manage a highly available container infrastructure. This
talk will explore DC/OS (the datacenter operating system) an
open-source, distributed operating system based on the
Apache Mesos[3] distributed systems kernel. DC/OS manages multiple
machines in the cloud or on-premises from a single interface; deploys
containers, distributed services, and legacy applications into those
machines; and provides networking, service discovery and resource
management to keep the services running and communicating with each other.

A demo using real streaming will also be given to show how DC/OS can
easily use various popular open source big data tools to process data
coming in and present it to the user.

Bio: Elizabeth K. Joseph spent much of the past decade working as a
Linux systems administrator, and today works as a Developer Advocate at
Mesosphere[4]. She is the author of Common OpenStack Deployments[5]
and The Official Ubuntu Book[6].
