Hash table vulnerability (property overwrite)?

和自甴很熟 提交于 2019-12-23 07:48:12
问题 I was playing around with hash tables in PowerShell, and I noticed some odd behavior related to accessing items. As we know, PowerShell allows at least three different ways of assigning values to hash table entries: $hashtable["foo"] = "bar" #1 $hashtable.Item("foo") = "bar" #2 $hashtable.foo = "bar" #3 Meanwhile, we use the #3 syntax to access the properties of the Hashtable object itself, such as Count , Keys , Values , etc. And if we add an item with the key that conflicts with the name of

Handling sensitive information with Puppet

纵饮孤独 提交于 2019-12-23 06:49:17
问题 What is the best way to store and handle sensitive information with puppet and safely distribute it to your nodes? The version I am using is 2.7. One example would be database passwords. Plain text passwords are needed on your application servers. How can one store these without leaving them lying around inside of the puppet scripts? 回答1: Using Hiera for external data lookups and encrypting that data via eyaml or GPG is a good start. https://docs.puppet.com/hiera/ https://puppet.com/blog

Why is SSLCertificateKeyFile needed for Apache?

£可爱£侵袭症+ 提交于 2019-12-23 06:48:16
问题 What's the technical reason that SSLCertificateKeyFile is needed (the private key)? Where is that used and for what? 回答1: The SSL certificate file contains the X.509 certificate (which, in turn, contains a public key used for encryption). The SSL Certificate Key File contains the private key corresponding to the public key in the certificate. In order for the webserver to encrypt and decrypt traffic, it must have both the public key (certificate) and corresponding private key. Apache, unlike

问题 I want to secure some forms that are placed on third party sites and submit to our little in house affiliate app. What is involved to encrypt forms between sites? Is SSL on the receiving domain sufficient? or does the page the form sits on need to be https too? 回答1: Essentially, you could do it two ways. One simple way is to use HTTPS and but thats as long as both can be HTTPS. They must also both have SSL certificates. Another way is to POST the forms locally encrypt/secure the data, then do

问题 I am loading assembly B from assembly A. I am trying to enumerate private members of the type located in assembly B. How do I use ReflectionPermission to accomplish this task?

how to prevent external xml file modification?

╄→гoц情女王★ 提交于 2019-12-23 05:48:09
问题 I'm coding a little library which will handle xml files to store some data, and I need this data to be handled only by the methods I provide in my library. I know that xml is readable for both human and machine, and that if somebody really wants to modify the xml file he'll probably do it, so... do any of you have an idea that could work? 回答1: You can store more information in it, such as a hash of the content (before the hash was inserted of course). When you will reload this file, you can

How come open source applications that are targeted at enterprises, don't have these security features? [closed]

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 4 years ago . It would seem to me that many large enterprises already have robust directory services such as Active Directory and it would be silly to constantly duplicate users in an application-specific store. Even if you require duplicating the user store, you can provide a mechanism to
