Given the sensitivity of the customer data stored in Gemfury, security is always on our mind. And with a renewed community focus on Rails security, I hope that our new Gemfury Security Series of articles will help ease your mind about using and building cloud services. Some have stated that our attempt at claiming "security" is bogus, and that your account can be easily exposed by sniffing the connection URL despite SSL.
This is not true! The basis of this statement lies in the layered manner HTTP connections are built. These layers are logically isolated, and when two computers connect, each layer communicates with the corresponding layer in the other computer without the awareness of the other layers. As you can see, once a client connects to a server, SSL session is established before the HTTP handshake takes place, ensuring that everything secret stays secret.
To focus on the basics, I intentionaly overlooked a few things keep-alive connections, etc. In those situations, the security principles still hold.
Secure your site with HTTPS
Although URLs are secure over the wire, there is no convention of keeping them secure once they've reached the server. If you are not careful, those URLs can leak to your server logs and external analytics providers. Another vulnerability is the Referrer header for subsequent requests. The secret URL will be sent as the referrer to any asset image, script, etciframe, or clicked link that's included in that page.
This is not encrypted. The client intitates a TCP connection by contacting the server by its IP, specifying the connection port. The two parties acknowledge each other's intent to connect and thus establish a TCP connection. TCP provides the concept of a connection insuring that all packets are received as intended.
By connecting to a secure port, the client has implicitly indicated to the server the need for SSL. At this point, the two parties negotiate a shared secret used to encrypt the connection. Everything past this point is encrypted and secure. The client initiates the HTTP request by sending the path and query portion of the URLthe headers cookies, user agent, etcand the optional request body like your Gem file.
The server replies with its HTTP response and terminates the connection. Notes To focus on the basics, I intentionaly overlooked a few things keep-alive connections, etc.In our opinion, this breaks norms in the security industry for Responsible Disclosurepotentially breaks norms around advertising without reasonable substantiation, and also brings to question the very motive behind the approach and its relevance to actually helping student safety.
Securly is choosing to keep this discussion focused on facts, technology and student safety.
Secure Options for URL Shortening
In this article, we provide a multi-step technical take on all the information being circulated. With facts and data, we proceed to distill truth from competitive marketing. The article is split into the following sections:. When Securly was founded 5 years ago, we started with a proprietary database we built via crawling of millions of websites, and we have continuously added and deprecated thousands of sites weekly to this database. As a result, the technology is a combination of a static database and a machine-learning AI component called PageScan that continually looks at sites our millions of students are visiting, and categorizes them in real-time to be added to the static database.
Our approach is the industry standard in the Enterprise Security space, and is definitely not an approach that we claim to have pioneered. This is a decade old approach that merits no advertising. Almost all web-filtering companies would have something comparable in place.
Note: The time between when a student browses a website and when it gets added to PageScan is 2 seconds. The video below shows PageScan catching sites we deliberately removed for a test account, and its process of automatically including and blocking new sites within seconds of the first visit by a student.
It must be noted that sites that were classified by PageScan were making it to our US West and all other databases. Responsible Disclosure would have allowed Securly to address such concerns ahead of a nationwide campaign to disseminate incomplete information.
From various sources, we were able to determine the nature of the sites used by LightSpeed for their tests.
However, we wanted to see how our PageScan technology performed in a scientifically sound experiment. This is a powerful statement. We have to balance the sensitivity of TextScan with False Alarms from it as overblocking in schools impedes instruction. There are many other ideas we will be working on including additional heuristics, better crowdsourcing, sentiment analysis, etc. Furthermore, LightSpeed itself uses comparable approaches, and so does the entire web-filtering industry, for decades.
With this technical report, we have attempted to explain how an industry-standard world-class system like ours works, and what kind of effectiveness to expect out of such a system.Colours marathi balumama serial

Here are the sources of websites used by our PageScan technology: Crowd-sourced URL scanning : When a Securly student goes to a website that is NOT in one of our denylists, the website is let through the first time only.
That website then goes through PageScan which dynamically categorizes the site as belonging to one of the following categories — pornography, gambling, games, and anonymous proxies. Search-engine crawling : Apart from PageScan, we also crawl search engines periodically for top adult keywords kids could potentially be searching, and then update our databases with top 50 sites from each of these keyword searches in case we missed any site.
Multiple images are downloaded from the site, and scanned using proprietary algorithms that detect pornography in these images. This technology is also capable of detecting other categories like violence, drugs, etc. These subscriptions are expensive enough to not be our first line of defense against new sites.
They come into the picture only when Securly is not able to decisively catch adult sites algorithmically first.What is the best PHP encrypt url class? Secure URL encryption.

A handy link is provided, but something stops you from clicking. Is this a legitimate link or a trick? Are you heading to a real website or are you opening your computer to a virus or malware? When faced with a "to click or not to click" decision, stop, take a step back, and do some investigating.P07e8 code
Tools, techniques, and common sense can help you figure out what's real and what's dangerous. If you're dealing with an embedded link, you can't see the URL automatically.
Hover your cursor over the link to reveal the URL without clicking on it and accessing its destination site.
One clue that your link may be dangerous is that the URL seems too short. While link-shortening services such as Bitly are popular and common tools for creating shorter links, malware distributors and phishers use link shortening to conceal their links' true destinations. You can't tell if a short link is dangerous just by looking at it.
Use a link-expansion service such as ChecShortURL to reveal a short link's true intended destination. Some link-expander sites even tell you if the link is on a list of known "bad sites. A common phishing ploy is to send an email that seems as if it comes from your bank. These emails usually instruct victims to "verify your information" by clicking on a link, ostensibly to go to the bank's website.
If you received an unsolicited email that is supposedly from your bank asking you to click on a link, then you are likely the target of a phishing attack.
Even if the link to your bank looks legitimate, don't click on it. Visit your bank's website via your web browser, either by entering its address or accessing a bookmark. This advice holds true for unsolicited texts from your "bank," as well.
Hackers and malware distributors often will try to conceal the destination of malware or phishing sites by using what is known as URL encoding. Using encoding, hackers and malware distributors can mask destinations, commands, and other nasty stuff within a link so that you can't read it.
They index the remote destination and then report back on what was found so you never have to load the site on your own computer. Take advantage of any active or real-time scanning options provided by your anti-malware software. Make sure your software is set to auto-update on a regular basis and check the date of its last update to ensure that updates are actually taking place.
