It’s a busy time of year (isn’t it always?) and you’re keen to get your hands on the latest gizmo, those hard-to-find gig tickets or a holiday in the sun … anything you buy online. Back to the gizmo, so you google, say, notonthehighstreet.com Click on the link, and up pops notonhehighstreet.com – and there’s your gizmo right on the home page. Click ‘buy’, click ‘pay’ … job done, and it’s next-day delivery.
However, if you think harder about it, it turns out that it makes perfect sense: you (the user) may know that you have a “safe” connection to a particular zone (say, the Intranet) and hence any content that is coming from that Zone can be transfered without HTTPS but remain secure (say, because your organization’s firewall prevents tampering by external attackers). In contrast, if you were visiting a HTTPS page on your Intranet, and it tried to pull in insecure content from the Internet, it would be incorrect for the browser to say “Well, the outer page is trusted, so we’ll let unprotected content from another source be mixed in.”
I’ll throw out https://secure.pugetsoundsoftware.com. That’s just a little example site of my own, but it has a valid certificate and displays a little green padlock to the left of the URL (in Chrome).
SSL stands for Secure Socket Layer. It’s the industry-standard security technology for encrypting information sent between a web server (i.e. your website) and a visitor’s web browser. SSL ensures the link between the server and browser is private and secure, safeguarding any sensitive information sent between the two. A valid SSL certificate proves that your site is protected.
You don’t need “two copies” of the shared files– you can have one server that delivers both secure and insecure content, and simply have two urls (one HTTP and one HTTPS) that points to that same server and file.
Thanks, as always, for your prompt response. Yes, I understand that, and appreciate the link. I was afraid there would be no way around this. Unfortunately, clients many times have to purchase SSL’s for this. Seems pretty silly to have to purchase a licence to make a server secure when it doesn’t really need to be, and in actuality, is only being done to stop IE from asking the user about mixed content!
What types of Mixed Content are blocked by default and what types are not? The browser security community has divided mixed content into two categories: Mixed Active Content (like scripts) and Mixed Passive Content (like images). Mixed Active Content is considered more dangerous than Mixed Passive Content because the former can alter the behavior of an HTTPS page and potentially steal sensitive data from users. Firefox 23+ will block Mixed Active Content by default, but allows Mixed Passive Content on HTTPS pages. For more information on the differences between Mixed Active and Mixed Passive Content, see here.
With the gift giving season coming up, many people will be doing their holiday shopping online. In fact, Americans will spend an estimated $61 billion shopping online this holiday season. Even mobile shopping is up 25% since last year.
HTTPS has been shown vulnerable to a range of traffic analysis attacks. Traffic analysis attacks are a type of side-channel attack that relies on variations in the timing and size of traffic in order to infer properties about the encrypted traffic itself. Traffic analysis is possible because SSL/TLS encryption changes the contents of traffic, but has minimal impact on the size and timing of traffic. In May 2010, a research paper by researchers from Microsoft Research and Indiana University discovered that detailed sensitive user data can be inferred from side channels such as packet sizes. More specifically, the researchers found that an eavesdropper can infer the illnesses/medications/surgeries of the user, his/her family income and investment secrets, despite HTTPS protection in several high-profile, top-of-the-line web applications in healthcare, taxation, investment and web search. Although this work demonstrated vulnerability of HTTPS to traffic analysis, the approach presented by the authors required manual analysis and focused specifically on web applications protected by HTTPS.
Eric, I’ve got a web app that should run over HTTPS. However, we as many other have, are running into the mixed content issue. The application in question is Activ-x-based and uses java scripting. Via Fiddler I can see no calls to any other web site other than the proper URL. However, our developers seem to think that the issue is casued by the Active-x component accessing files that are stored on the local PC’s file system, outside of the Browser’s cache. The app allows users to select a batch of documents that has been scanned and stored on the server for review. The client downloads a set of thumbnail representations of the full sized images and stpres them in a set of applciation-specific folders. We believe that IE is viewing the locahost’s file system as a zone separate from Internet, Intranet or Trusted. Any thoughts?
Depending on how a site is hosted and where, there are various ways of adding an SSL certificate. In some cases, if there’s an ecommerce element on the site, it will be a requirement to have a certificate. Major hosting providers often offer hosting packages including SSL certificates.
The best solution, of course, is to make sure that these warnings and/or blocks won’t occur in the first place by correctly configuring your site to serve only secure content. A mixed-content warning means that there are both secured and unsecured elements being served up on a page that should be completely encrypted. Any page using an HTTPS address must have all of the content within coming from a secured source. Any page that links to an HTTP resource is considered insecure and is subsequently flagged by your browser as a security risk.
Your website’s pages and posts also store data in certain tables of your database. You’ll need to make sure to search and replace any non-secure URL for your domain with the secure version of your domain’s URL. We’ll walk you through two steps on how to achieve this.
The support team and my account manager were super helpful to work with. Very professional, extremely patient, and friendly! it has been such a great experience to work with them. I would highly recommend GlobalSign to anyone.
I have no idea why this is happening other than the fact that Microsoft has many servers and perhaps you just happen to be sent to ones with different levels of encryption. For a normal user, 128 bit should provide sufficient protection as it would take a super computer a long time to crack that at an extremely high cost.
Good information & easy to understand…but still have to jump through hoops to check each situation…through no fault of yours…thanks for the much appreciated information. I just tried…the ssl & found that the dmv site for me to renew my vehicle registation was not a secure site..even though I have firewall on my laptop…the premature comment was just that. I apologize for commenting before actually trying it out. Lesson learned thanks to your consise direction for a safe experience on the web. Approved: 7/20/2011
By using the most secure form of certificate – the Extended Validation SSL certificate – the company name appears in green in the address bar. It’s another sure-fire way of letting customers know that it’s 100% legitimate.
To provide the server name, RFC 4366 Transport Layer Security (TLS) Extensions allow clients to include a Server Name Indication extension (SNI) in the extended ClientHello message. This extension hints the server immediately which name the client wishes to connect to, so the server can select the appropriate certificate to send to the clients.
As well as encryption, Certificate Authorities (CAs) can also authenticate the identity of the owner of a website, adding another layer of security. The SSL certificate is then used as proof of the company’s identity. Certificates can be divided into three authentication groups, based on the level of authentication, which are:
For a personal blog, hobby site, or any website that doesn’t represent a business, we recommend our Domain Validated SSL service. A Domain Validated SSL certificate is quick and easy to install, encrypts all page views, provides a green padlock icon in the browser address bar, and validates your domain name via email.
You will usually be asked for a password before you make an online payment. This is to help keep your personal details private. Make sure you use a strong password – one that is a combination of letters (upper and lower case), numbers and symbols.
Some people just look for a lock on the page, not on the browser. After you’ve installed SSL you might want to try adding a lock icon on your pages just to let them know it’s secure if they don’t look in the url bar.
Browser checks the certificate root against a list of trusted CAs and that the certificate is unexpired, unrevoked, and that its common name is valid for the website that it is connecting to. If the browser trusts the certificate, it creates, encrypts, and sends back a symmetric session key using the server’s public key.
When you go to a site that uses HTTPS (connection security), the website’s server uses a certificate to prove the website’s identity to browsers, like Chrome. Anyone can create a certificate claiming to be whatever website they want.
Personally, if a plugin throws WP_DEBUG errors, sets off security errors, or loads assets on pages where it doesn’t belong, I usually get rid of it altogether. If I have the time and the plugin is valuable enough, sometimes I report the error or even provide the fix, especially if the plugin author has enough credibility that I know this is an infrequent occurrence.
A protocol downgrade attack (also called a version rollback attack) tricks a web server into negotiating connections with previous versions of TLS (such as SSLv2) that have long since been abandoned as insecure.
According to Business Insider 74% of shoping carts are abandoned but up to 64% can be recovered with better checkout security and flow. Many of these 64% are more likely to complete a purchase if they know the checkout area is secure. That’s not a number businesses can afford to ignore. Even if they’re only using SSL for their checkout area, it’s well worth it.
I keep getting the yellow triangle with exclamation point on my bank website, where the login is! I am terrified to trust it without updated certificates. How do I go about getting the proper certificates in Chrome?? I guess I dont even know where these “certificates” come from. Can they be downloaded? In settings, I find a spot that has trusted certificates listed. Go Daddy is one of them, but Chase Bank is not?? But I have no idea where to acquire them if I need one! Any advice?
Root programs generally provide a set of valid purposes with the certificates they include. For instance, some CAs may be considered trusted for issuing TLS server certificates, but not for code signing certificates. This is indicated with a set of trust bits in a root certificate storage system.
Before I make any transaction with my credit card, I always look at the address bar at the top to see if it begins with https and that there’s a closed golden padlock at the extreme right of the bar. Then and only then will I proceed. Recently, I’ve come across a couple of trusted and/or reputable sites which do exhibit the https part, but the padlock is missing. Instead, they have sort of a reassurance like “your order is safe and secure with all SSL 128 or 256 blah, blah” lower down where you enter all of your personal details and credit card number. Now what would I like to know is this safe? Even though the vendor’s site is reputable and it’s recommended by an equally reputable person? At the best of times, I’m rather paranoid about giving my personal details to an invisible entity so when it comes to credit card details and such, my distrust knows no bounds. Am I being overly cautious or am I being justified somewhat reticent?
Although Internet Explorer comes with built-in security screening settings, it has long been known for its vulnerability to malware and spyware. If your address bar does not reappear after standard troubleshooting steps, if you see a sudden drop in performance, or if your browser experiences other problems, your computer may be infected. PCWorld suggests that you start your computer in Safe Mode with Networking by holding down the “F8” key as the computer starts up. Download a new malware scanner — PCWorld recommends Bitdefender, ESET Online Scanner, or House Call — and scan the computer to find and remove malicious programs.
