How Audit Logs Help Confirm and Correct Security Policy
There are many possible definitions for the term “security policy,” but all of
them share certain elements in common. A security policy should lay out what
assets, both physical and digital, an organization wishes to protect. It should
explain what it means to be secure and to behave securely. In short, a security
policy identifies what assets are to be protected, what kinds of risks such
protection is meant to defeat or mitigate, and how security can be established,
measured, and monitored. A

Signal AND Noise The Best of All Worlds for Logging
One of the absolute, classic pieces of advice that you’ll hear when it comes to
logging is what I think of as the iconic Goldilocks logging advice. It goes
something like this.
When it comes to logging, you don’t want to miss anything important because
logging helps you understand your application’s behavior. But youalsodon’t want
to log too much. If you log too much, the log becomes useless. You want to log
just the right amount.
Sage advice, to be sure. Right?
Or, maybe, when you sto

Migrating a web app to Angular
At some point many applications get to a state in which a large refactoring or
in some cases a complete rewrite needs to happen. The decision to do so can be
driven by many factors. For example, the code base is growing rapidly and the
current architecture cannot support the growth, components are becoming too
tightly coupled and need to be split, new and better technology becomes
available which offers significant improvements or due to other factors the
current code base is just not maintain

Monitoring SNS Activity Using a Lambda Function and Logentries
Amazon Web Services Lambda functions are very cool. A Lambda function is a
feature in Amazon Web Services that allows you to put a discrete piece of
computing logic up in The Cloud and then access that logic to meet a particular
need. For example, you can create a Lambda function that takes a list of stock
symbols and does some analysis on the list using other cloud based services in
order to suggest the best stock to buy.
Logentries has put the power of Lambda functions

Checking Active Directory (AD) Security and Integrity via Log Monitoring
Because AD literally holds the keys to the kingdom for domain-based networks and
runtime environments, it’s usually a good idea to keep a close eye on those
keys, how they’re being used and what kinds of attacks might be directed at
them. Monitoring AD related event logs provides one great tool in exercising due
security and integrity diligence. Alerting on specific high-impact events
provides yet another.
For over two decades now, Microsoft’s Active Directory (AD) has provided a

Integrating Logentries With .NET The How and Why
A robust logging strategy opens up a world of potential improvements for your
.Net applications through application logging. Application logging provides
valuable insight. Insight that can only benefit your network application stack
since your .Net application is the front line for enhancing your customer’s
experience.
Bringing meaning to all the potential information that your .Net application can
collect is what Logentries does best. Logentries makes getting this valuable

Intrinsically fast: more JVM performance tinkering
I didn’t expect my last post
[/2016/03/14/a-point-of-contention-cache-coherence-on-the-jvm/] on JVM perf to
be so well received, so I thought I’d carry on digging into why your code does
(or doesn’t) run fast! Let’s forget about concurrency for now and instead focus
on the executable machine code that the Java Virtual Machine (and particularly
HotSpot) generates.
In Java-land it’s pretty common to hear people mention stuff about ‘warmup
times’, especially in the context of an incendiary micro

Implementing Self-Describing Log Data Using NodeJS

a technique that made structuring your logging information as key-value and

the same concepts to NodeJS. I’ll show you how to make it so that so you can

How To: Send Logentries Alerts to BigPanda
Working in customer support we are usually the first to receive feature
requests, integration requests or recommendations. We would then relay this to
our product team. But we often get requests that we can tackle ourselves whether
this may be small coding tasks or account changes. So when we heard a user
wanted to be able to forward their Logentries alerts to BigPanda.io, we made
that happen.
When any issues occur, time to resolution matters. Because Logentries streams

A Query Language for Your Logs
Application logging is the software world’s version of archeology. At runtime,
your application lives in a rich, colorful, 3-dimensional world of flowing
aqueducts, packed coliseums, and bustling streets. There’s more going on than
can possibly be captured.
When you’re trying to reproduce and correct a reported issue, you play
