Who’s Hacking My Exchange OWA? Check with Log Parser 2.2

I am one of the few on the planet that still hosts my own servers in house. Sorry, but I don’t really see the benefit of moving everything to the cloud when keeping it in house allows me the control and flexibility I want. I especially like having an Exchange OWA server in house.

With that said, hosting your own systems can be troublesome as well. Maintaining the hardware, infrastructure and security are items that would get farmed out in a cloud environment. This post focuses on the security end, or rather attempting to track hack attempts.

In January, I sent up a trigger to alert me every time a user is locked out. -> Know instantly when a user is locked out <- Its a good read if you’re interested. This trigger reads the event logs, looks for the lockout event and sends the info to me via email. A great help in being proactive with my users. It also alerts me to hack attempts. Too many incorrect login attempts on OWA would trigger a lockout event. During a recent weekend, I was receiving lockout emails every 30 minutes. So who was doing this? What did they want?

2013 – 2018 Lexus GS 350 Cabin Filter Replacement Procedure

Once a year I change my air filter and cabin filter to help keep my GS 350 performing at its best. The Lexus dealer can charge upwards of $150 for each of these services. You can save yourself hundreds of dollars if you take 5 to 10 minutes to do it yourself. In this post I will show how easy it is to swap out the GS cabin filter. Click this LINK to see how easy it is to change the Air filter.

Where to get the correct Cabin Filter?

I believe many Lexus models take the same cabin filter. I searched on Amazon and many of the filters i came across said they were NOT a match for my car. Finally I found this EcoGard filter that said it was going to be a good fit, I took a chance and made the purchase.

EcoGard filter for GS350 $16.54 at Amazon.com

There are lots of other compatible filters. Picking a cabin filter is more a personal preference since they are a creature comfort and will not affect the performance of the car. Use this link to search all of Amazon for filters that should fit the GS 350 – CLICK ME

2013-2018 Lexus GS 350 Air Filter Replacement Procedure

My 2017 Lexus GS 350 needs a new air filter. It’s been about 20,000 miles and is ready for a replacement. No matter what car I drive, weather it be a $500 Honda Accord or my GS I’m still a do-it-yourself kind of guy and refuse to hand over money for something I can easily do on my own. The Lexus dealer can and will charge upwards of $150 to replace the air filter. If you follow my instructions below I will save you over $100 and have your car done in 5 to 10 minutes!

Where to get the correct air filter?

I like to shop on Amazon, they usually have great prices and with my prime membership the orders arrive at my door super quick.

There are quite a few manufactures that make replacement filters for the GS, I tend to steer toward name brands I trust and have used in the past.

Fram is my first choice in filter, they tend to be slightly more expensive than other brands, but they perform well and last. This particular filter has an extra layer of filtration material on the bottom. I haven’t seen that previously on others. I’m curious if it adds that much more filtration without cutting down the airflow to the engine. $33.99 at Amazon Continue reading “2013-2018 Lexus GS 350 Air Filter Replacement Procedure”
