## Need a conceptual illustration of “Security Software Stack Elements” at (a) Endpoints (b) Servers (c) Central Ops (Control/Console) [on hold]

Need a conceptual illustration of “Security Software Stack Elements” at (a) Endpoints (b) Servers (c) Central Ops (Control/Console)

Endpoint : Antivirus, USB/Port blocking, Malware/Ransomware detection (ie ATP, FireEye) , Proxy for controlling end user web surfing (ie ZScaler), DLP, Rights Management Services (RMS), MDM

Servers : Server ANtiVirus, Lockdown of Server-to-Server communications, Server exe fingerprinting/checksumming, etc

Central Console : Logs, COnsolidated Reporting, Analysis

There are so many tools, but they overlap and its not clear what software does what and therefore the need for a key checklist of endpoint and server-side security functionality required.

Hence request a list if someone has made a good/useful diagram…

## Can’t get in Central Administration

Apparently within the last 3-4 weeks we lost our ability to get into Central Administration. Now when I or the other SA tries to get to the URL with port it asks us to authenticate again and doesn’t take our credentials. (Directly on server, as we’ve always done it.) Tried our domain accounts and local admin account on the box.

We were trying to get in there because some Sharepoint database on C: exploded in size the last week or so and filled up the drive and the setting is in… Central Administration. It’s awesome troubleshooting an interface to be able to get in to troubleshoot the initial problem.

No changes have been made on this server as the departing SharePoint guy apparently left them in a test OU with no GPOs, it doesn’t have firewall/McAfee… Not sure what could have changed.

## “Report Server Central Administration Feature” is missing in Central Administration Site collection features

I am using SharePoint Server 2016 and SQL Server 2016 SP1. I installed “Reporting Services – SharePoint” feature on the Application server(Custom Role) and “Reporting Services Add-in for SharePoint Products” feature on the Web Front-end Server. I am also able to create the “SQL Server Reporting Services Service Application”.

We have migrated from SharePoint 2013 to SharePoint 2016 and have a Document library with below reporting content types:

• Report Builder Model
• Report Builder Report
• Report Data Source

After migration I see some faulty content types in target environment. Refer to below screen-shot.

from the above image I was able to understand the features may not be activated. But I could not find the reporting services features in Central Administration and site collection to activate them. Below are the features am looking for.

• “Power View Integration Feature” site collection feature.

## Comparison between central logic or distributed logic in microservices?

I’m designing an application in a microservices architecture. The app has its own logic but also needs to collaborate with other services.

For example, the app is A, and other apps are B and C. Whenever there’s an event “X” happens in A, The B and C also need to do something like sth-B(), sth-C().

There are two ways that I can think of:

1. Keep the logic in A. So A will know all the things to do when event “X” happens. It will do sth-A(), then call restful sth-B() and sth-C(). B and C are simply passive.
2. Distribute logic to B and C. So A will only do sth-A() and publish the event "X" into a message queue. B and C will subscribe the event and do sth-B() and do sth-C() respectively. In this way, A doesn’t need to care about what subscribers do, but it’s hard to know what in the whole system are really being done when the event happens.

My questions are 1) are the above two design ways common? Do they have formal names? 2) Which one should I choose in a microservices architecture?

## Problem mounting a segate central HDD in ubuntu. Can anyone help?

Hey so im trying to get my data back from a segate central hdd that died on me (I suppose it died because its OS crashed somehow) the thing is the hdd is pretty much functional by itself but its full of data that i just cant access and that id like to get back.

Here are some things me and a friend tried to do:

 @GladOS:~$sudo mount -r --source /dev/sdb8 --target /mnt/segate mount: /mnt/segate: unknown filesystem type 'LVM2_member'. @GladOS:~$   sudo apt install lvm2   @GladOS:~$sudo mount /dev/vg1 /mnt/segate mount: /mnt/segate: special device /dev/vg1 does not exist. @GladOS:~$   sudo mount  PARTUUID=W7LlYP-QbJO-Ipkp-lIOb-yWTX-3HK1-B4ca22 /mnt/segate mount: /mnt/segate: can't find PARTUUID=W7LlYP-QbJO-Ipkp-lIOb-yWTX-3HK1-B4ca22. 

## Local central limit theorem far from the center

Let $$X_i$$ be a sequence of iid random variables, $$E [X] = 0$$, $$E [X^2] = 1$$ and $$E [|X|^k] < \infty$$ for some $$k \ge 3$$. Classical local CLT says that the density function $$f_n$$ of $$\frac1{\sqrt n}\sum_1^n X_i$$ satisfies that $$f_n(x) – \phi(x)\left(1 + \sum_{j=1}^{k-2} n^{-\frac j2}P_j(x)\right) = o\left(n^{-\frac{k-2}2}\right), \quad \phi(x) = \frac1{\sqrt{2\pi}}e^{-\frac{x^2}2}$$ where $$P_j$$ is some $$(j + 2)$$-order polynomial, and the RHS is uniformly small for $$x \in R$$.

This gives us very good estimate for constant $$x$$. My question is that can we get a similar expansion equation for $$f_n(\sqrt nx)$$? Since $$\phi(\sqrt nx)$$ decays faster than any polynomial order in $$n$$, we can not apply the local CLT directly.

Remark: I consider this in order to estimating the following expression for $$x \not= 0$$ and $$y$$: $$\frac1{f_n(\sqrt nx)}f_{n-1}\left(\frac{nx + y}{\sqrt{n-1}}\right), \quad n \text{ sufficiently large}.$$ When $$x = 0$$ by local CLT this is bounded by $$1 + C(1+y^2)/n + o(1/n)$$. If $$x \not= 0$$, I expect the upper bound $$\exp\left\{-\frac{x^2}2 – xy\right\}\left[1 + \frac{C(x^2 + y^2)}n + o\left(\frac1n\right)\right].$$

## Difference between local and central anti-spam

I’m attending a web security course whose slides, concerning techniques for protecting ourselves from spam, sometimes report the expressions “local anti-spam” (or “personal anti-spam”) and “central anti-spam”.

I suppose the “central anti-spam” is the e-mail provider’s one, but I cannot figure out what can be a local (or personal) anti-spam and which can be the differences about them.

I tried to google such expressions but I didn’t find anything.

## Como o android manda um código de alarme para a central de monitoramento?

Estou criando para android um sistema de emergência, um app para se comunicar com a central de monitoramento. Evidentemente deve ser com o contact id Procol.

Como no exemplo acima. Eu achei em How to send a Contact ID alarm to the Central Station from a C# application over VoIP , algo como esperava mas esta para C# não sei nada dessa linguagem para poder fazer uso disso. Contudo, parece não existir conteúdo para Java.

Alguém conhece como faço o android mandar os códigos contact id para a central de monitoramento?

Detalhe, parece que no exemplo que achei ele cria um simuldador de telefone registrando ele na rede e mandando posteriormente a informação. Se é que entendi o processo. Bem, o app vai estar instalado no android, será que isso é necessário mesmo?

Há vários apps para IOS e Android que fazem essa ligação. Como por exemplo o paradox e o da intelbras.

## How do I install from Maven Central?

I’m trying to install this but I’m unfamiliar with Maven and I have no idea how to follow the installation instructions: https://github.com/twosigma/flint (it’s one of those “so basic nobody bothers to state it on the internet” questions)

According to that link “Scala artifact is published in maven central” – so how do I get that thing installed where Spark (and ultimately pyspark) can use it?

For apt it would just be apt-get install xyz
For pip it would just be pip install xyz

so why isn’t mvn install flint working for me?
