integrity

This question is related to another existing SO question . HttpServletRequest's getSession(boolean) method mentions session integrity, but it does not define the concept. I could not find an offical definition. Is there any? Does anyone know what rules formally define when a session is in or out of integrity? Thanks. It refers to the concept of linking the server session with the client (web browser) session with a cookie. I'm not sure how familiar you are with java web apps, but the Servlet containers can track sessions by adding a parameter to the url (usually called jsessionid) or by

I have learned that secure world can protect critical data from being accessed by normal world, What I don't understand is that how do I measure the integrity of normal world from secure world. I find some relevant work in the Samsung TZ-RKP and SierraTEE , in which they both implement a feature that could measure the integrity of normal world. But they didn't give technical details. I have two questions and I'd appreciate it very much if anyone could give me some clues. Suppose I want to see what processes are running in the normal world, do I have to use a kernel module in the normal world

I have an API endpoint where external websites can submit a POST request. What would be the best method to make sure the requests are authentic and also are not tampered with, so they respect the principle of integrity ? Since the data is not valuable such as credit card information, I do not require HTTPS integration. I have had a look at both HMACs and Digital Signatures, and I believe the second option would be better, yet I am unsure if this is the way to go? Similarly, would hashing the request and verifying it on my server be enough? Both HMAC and Digital signature provides integrity and

How I can create named pipe in the Windows 8 with AppContainer integrity level? Roman Boiko As Pavel Minaev mentioned in one of comments to some answer , there are no named pipes in WinRT (for Metro applications, for desktop applications pipes are the same as in Windows 7): Named pipes aren't there, for example, nor are memory mapped files. There are sockets (including server sockets), but when connecting to localhost, you can only connect to the same app. You may be interested in the WinRT API , including sockets . Talking about WinRT - you really can't create named pipe. Talking about

I am in the middle of designing a system that will be used to feed several production sites around the country (all information is in one site) with the potential to add more. Initially I thought that I could get away with only using one database. I am now re-thinking my original design and leaning toward a more scalable solution. Keeping down the size of each database / tables is also important. There will be a "master" database that has information that spans the notion of a site and then a separate database for each site with site-specific information in it. My struggle is where to separate

I have a model with two fields as below models.py class Publisher(models.Model): name = models.CharField(max_length=200) slug = models.SlugField(max_length=150, unique=True) def save(self, *args, **kwargs): if not self.id and not self.slug: slug = slugify(self.name) try: slug_exits = Publisher.objects.get(slug=slug) if slug_exits: self.slug = slug + '_1' except Publisher.DoesNotExist: self.slug = slug super(Publisher, self).save(*args, **kwargs) Here i am creating a slug based on the name field as we can see above So when we try to create a publisher with name already exists , the save method
