Hidden and protected

Hello, can somebody explain what is the difference between "hidden" and "hidden and protected" items and give examples when one should be used and not the other - like why should I use "hidden and protected" as opose to "hidden" or vice versa.

George,
User's Guide --
Hidden and Protected
Renders an HTML hidden form element. Session state can be assigned and referenced just like a text field. For maximum security use Hidden and Protected instead of Hidden unless your page has client-side behavior, for example, JavaScript that alters the item value after the page is rendered by Oracle Application Express.

ERROR -- Checksum error for Hidden and Protected item ID

Hello all,
I usually get the error:
Checksum error for Hidden and Protected item ID (10785219011206310), value (on), posted checksum (C1DEF33B4C8D57845151B7D18363B3D7), expected checksum (********************************), index_i (3), index_j (2), index_m (1);
I have already found one thread with this question - Checksum error for Hidden and Protected item ID
but there are no answers to this problem.
Any thoughts how to solve this and what is causing it??
Regards Pedro.

Pedro,
Read under the improved security section in the below article.
http://www.oracle.com/technology/products/database/application_express/html/3.1_new_features.html
I used to receive the same error because I was trying to update the value of the hidden and protected item on the same page repeatedly.
I changed the item type to hidden to avoid the error.
Hope this helps,
Dippy

Checksum error for Hidden and Protected item ID

Hi,
I created an icon which is called 'Find an employee'. When a clicked on that icon, it shows employee id and employee name. And near these names there is a select button. But, it gives the following error:
Checksum error for Hidden and Protected item ID (1558647128276141385), value (KING ), posted checksum (3F6EC88428199012945F76490A29168B), expected checksum (********************************), index_i (4), index_j (3), index_m (3);
Is there anyone who knows the reason of this error?

Checksum error for Hidden and Protected item

I have a region with 3 items - a Text field, a Text area and a Hidden and Protected item. When clicking on the save button the record should be written to the table. However I get the following error:
++Checksum error for Hidden and Protected item ID (7676217916943303), value (), posted checksum (1060941776BCEA7DDAE813A442DF01E3), expected checksum (********************************), index_i (8), index_j (1), index_m (3);++
When I change the hidden and protected field to a regular text field I am able to successfully process the page.
Do I have to do anything different when I have a hidden and protected field? Would appreciate any suggestions/comments to help resolve this issue.
Regards,
Ghazi

If you have client-side code that changes the value of a "Hidden and Protected" item after the item/value has been emitted to the page by Application Express, you need to change the item type to Hidden, instead.

Hi,
The problem is when you are creating an item "Hidden and protected" so apex will associate a checksum value for that item's value and as you are changing the value, the checksum will not changed.
If there is no security issue use "Hidden" instead of "Hidden and protected" for that item.

Hidden items in apex 4 now hidden and proteced

Hi all,
The option hidden and proteced is no longer available in Apex 4. Now a hidden item is automatically hidden and proteced.
This gives me problems with my app.
I created a page with a menu.
When I click on the menu my page gets filled with content.
I do this with a text item.
In this text item I fill the content id. When I click on the menu a javascipt fills the text item with the correct content id.
The content region reads the content id and the content gets displayed.
Now if I set the text field as hidden, the page gives me an error
Error Checksum error for Hidden and Protected item ID (2036114079384286), value (5), posted checksum (8EDF8C5C97169E49A9A12B5B15897DB5), expected checksum (********************************), index_i (1), index_j (1), index_m (1);
Any suggestions?

Huh?
There's a type of "Hidden" and a separate place under "settings" for "Protected" and you answer Yes or No from the select-list.
Does this not work for you?

HT203167 A movie I purchased in the iTunes store is missing. It isn't hidden and doesn't show up in search. I've followed support steps. Where is it and how do I find it? I believe I originally purchased the film on my 1st Gen AppleTV.

A movie I purchased in the iTunes store is missing. It isn't hidden and doesn't show up in search. I've followed support steps. Where is it and how do I find it? I believe I originally purchased the film on my 1st Gen AppleTV...other movies show up. Help.

It was Love Actually. It's been in my library a few years but is now missing. It's odd...it isn't even in the iTunes Store anymore. I think there is a rights issue because a message appeared in the store saying it wasn't available at this time in the U. S. store. Still, if I bought it years ago it should be in my library or I should get a refund....

I'm having some difficulty with Time Machine. It appears to be deleting backups from random dates on my external hard drive. I am not deleting them. Are they hidden and how do I prevent this from happening? Can I retrieve them?

I'm having some difficulty with Time Machine. It appears to be deleting backups from random dates on my external hard drive. I am not deleting them. Are they hidden and how do I prevent this from happening? Can I retrieve them?

... I didn't know that Time Machine was more a last resort back up instead of main back up.
Don't rely upon Time Machine to the exclusion of all else. I compliment Time Machine with a periodic "clone". TM is much better than nothing, but it's a safety net, not a hammock
Here is my understanding of Time Machine's file deletion algorithm, distilled from Pondini's FAQ, Apple's KB articles, and my own observations.
Time Machine deletes ("thins") files from the backup disk as follows:
Hourly backups over 24 hours old, except the first backup of the day
Daily backups over 30 days old, except the first backup of the week
Older backups get deleted when Time Machine requires space and you deleted them from the source disk.
Therefore, assuming TM has been performing at least one backup per day, backup files will remain available:
at least thirty days, if they existed on your Mac for at least a day
until you run out of space, if they existed on your Mac for at least a week
In addition to the above, Time Machine always keeps one complete copy of your source disk so that the entire volume could be restored if necessary. Any files that remain on your source volume will be present on the TM backup, no matter how old they are.
If you are using 250 GB of space on your source disk, its Time Machine backups are likely to require at least twice that much. A good estimate of the minimum required backup volume size would be about three times the size of your source disk - 1.5 TB in your case.
A more thorough explanation would require Pondini since he has plumbed Time Machine's mysteries far more than I have.

Dynamic Parameter Page - Hidden and Required fields

Post Author: robfurrball
CA Forum: .NET
Product: CR 10
Version: 10.0.0.5.1279
Operating System(s): XP
Database(s): SQL Server All, This is my first forum post, so please excuse any mistakes...I believe this is the right forum for the topic. I'm working on a page that will dynamically read the parameters in a CR report requested by a user and will build and display an input for each parameter (datepicker for date, drop down list for discrete values, etc.) I'm looking at how to define whether a parameter should be hidden (ex. username - populated by a session variable) or required (ex. Customer Name - would like to bold or put a special character next to the label/prompting text to show that it is required). The best that I've come up with would be to define a naming scheme like @_variable for hidden and @#variable for required. Is there another way that this could be done in case other groups want to use this page to load reports in the future, but may not have those naming schemes enforced? Thanks,Rob

I want to know the questions and protection for my account because my account is locked I can not buy please help

The page that you posted from tells you how to reset them i.e. if you have a rescue email address (which is not the same thing as an alternate email address) set up on your account then steps 1 to 5 half-way down that page should let you reset them.
If you don't have a rescue email address (you won't be able to add one until you can answer 2 of your questions) then you will need to contact iTunes Support / Apple to get the questions reset.
Contacting Apple about account security : http://support.apple.com/kb/HT5699
When they've been reset (and if you don't already have a rescue email address) you can then use the steps half-way down the HT5312 page that you posted from to add a rescue email address for potential future use

What is the best malwear detection and protection for use on a Mac?

What is the best malwear detection and protection for use on a Mac?

Mac users often ask whether they should install "anti-virus" software. The answer usually given on ASC is "no." The answer is right, but it may give the wrong impression that there is no threat from what are loosely called "viruses." There is a threat, and you need to educate yourself about it.
1. This is a comment on what you should—and should not—do to protect yourself from malicious software ("malware") that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the computer, or who has been able to log in to it remotely. That threat is in a different category, and there's no easy way to defend against it.
The comment is long because the issue is complex. The key points are in sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user. Internally Apple calls it "XProtect."
The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
☞ It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
☞ It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
☞ It can easily be disabled or overridden by the user.
☞ A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
☞ An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
Apple has so far failed to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. These failures don't involve App Store products, however.
For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is foremost a problem of human behavior, and no technological fix alone is going to solve it. Trusting software to protect you will only make you more vulnerable.
The best defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and Internet criminals. If you're better informed than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.
Software from an untrustworthy source
☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
☞ Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, or your browser, or any other software.
☞ Rogue websites such as Softonic, Soft32, and CNET Download distribute free applications that have been packaged in a superfluous "installer."
☞ The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.
Software that is plainly illegal or does something illegal
☞ High-priced commercial software such as Photoshop is "cracked" or "free."
☞ An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission. All "YouTube downloaders" are in this category, though not all are necessarily malicious.
Conditional or unsolicited offers from strangers
☞ A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
☞ A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one.
☞ You win a prize in a contest you never entered.
☞ Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.
☞ A "FREE WI-FI !!!" network advertises itself in a public place such as an airport, but is not provided by the management.
☞ Anything online that you would expect to pay for is "free."
Unexpected events
☞ A file is downloaded automatically when you visit a web page, with no other action on your part. Delete any such file without opening it.
☞ You open what you think is a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.
☞ An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
☞ Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.
I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it—not JavaScript—in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the left side of the address bar when visiting a secure site.
Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial "anti-virus" (AV) or "Internet security" products for the Mac, as they are all worse than useless. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else.
Why shouldn't you use commercial AV products?
☞ To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. This technique is a proven failure, as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry is coming to the realization that traditional AV software is worthless.
☞ Its design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, commercial AV software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
☞ By modifying the operating system, the software may also create weaknesses that could be exploited by malware attackers.
☞ Most importantly, a false sense of security is dangerous.
8. An AV product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject low-level code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An AV app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful, if at all, only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware.
Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else. A malicious attachment in email is usually easy to recognize by the name alone. An actual example:
London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an organizational policy requires it. Windows malware is so widespread that you should assume it's in every email attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application. It's free and it won't handicap the system.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user, you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither can you assume that you will always be safe from exploitation, no matter what you do. Navigating the Internet is like walking the streets of a big city. It's as safe or as dangerous as you choose to make it. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

Hiding and Protecting Fields for Input in SRM 4.0 (BSP) Shopping Cart

On the Shopping Cart transaction(s) BBPSSC01 to BBPSSC03, the HTML templates are under ITS SERVICE BBPACCOUNT, and the main HTML template is called saplbbp_pdh_acc_2000_1. We want to grey out the G/L Account field and hide the business area field.Is there any other way to satisfy this requirement besides making an actual change to the HTML/BSP page and publishing. After researching this for quite a while I could not find another mechanism to grey out or hide fields. If the page has to be changed it looks like they have a code check if the field is disabled, can we simply set that field to true and the field will be Greyed Out and protected from input?
